Soooo I had GD and high bp with my 2nd child. Guess when she was due? End of April. Guess when this baby is due? May 1st. I did not have either of those things with my son born November 5th and my 1st daughter born in July. Weird coincidence? Or possible other factor. I read in the hypnobabies material about how calcium can affect your blood pressure. Vitamin D is very important as well and needed for optimim calcium absorbtion. I will admit to not being the best at eating calcium rich foods. I did however yesterday go buy a calcium supplement. Anyway just thought I would throw that out there. What do you think?
one of the things I'm on to help make sure my bp stays down is a Mag/Cal supplement. Since I started it up, I haven't had a migraine and my bp has stayed down this time... just anidotial evidence, but it's one of the supplements I really try to remember and take...
Some docs will put a patient on supplemental calcium and magnesium during pregnancy to reduce the risk of high BP. However, the studies showing increased risk of PIH being correlated with calcium deficiency tend to be in populations that tend to have a calcium deficiency anyways....we're talking about societies where people don't drink milk or have calcium fortified foods/drinks. So my doc said that it wouldn't make a difference...especially since I'm a milk drinker. (I LOVE cow's milk! Probably shouldn't brag about that though...). Have you looked into taking low-dose (81 mg) aspirin in the 2nd half of pregnancy to prevent PIH? I've been taking it for a few weeks now, since my BP did spike up a bit at the end of my pregnancy with Jesse.
I don't drink a lot of milk. How does the low dose aspirin work?
I was advised not to touch asprin with a 20 foot pole by both OB, Family Doc and Midwives, but up to you I guess...
I started a calcium, magnesium, and zinc supplement on top of the prenatal multi vitamin, these were because as a Canadian we're prone to Vitamin D deficiency's and since becoming preggers I can't just pop in to a tanning bed twice a week to help that :P The Zinc and Magnesium are because they are high transfer minerals, both help with calcium, Vitamin D, Iron and other important things I'm deficient in.
All and all, since starting the supplements, I've had better energy, lower bp, feel more relaxed and I don't get every cold my kids drag in from school (or as the hubby puts it the plague ridden spawn infect him with) Hubby just started the Calcium/Zinc combo after I told him Zinc helps fend off the colds (he asked why I didn't get sick last week while DD#3 was in bed with us nearly every night coughing in our faces LOL)

Being that is *is* up to me, I'd much prefer to avoid PIH this time around if possible. Last time it almost resulted in an inducation at 38 weeks (when I had a VERY low Bishop's Score), and did result in 2 weeks of modified bed rest, not being able to drive or go anywhere but doctor's appointments, having a bunch of NSTs and BPPs that I would have rathered to avoid.Aspirin (Low Dose)
In women at increased risk of preeclampsia, low-dose aspirin
results in a small decrease in: preeclampsia (RR 0.85;
95% CI 0.78–0.92; NNT69; 95% CI 51–109 women; 43 trials,
33 439 women for this outcome), preterm delivery (RR
0.92, 95% CI 0.88–0.97; NNT 83; 95% CI 50–238 women),
and perinatal death (RR 0.86, 95% CI 0.75–0.98; NNT 227;
95% CI 128–909 women) (51 trials, 36 500 women overall).
180 There is no evidence of short- or long-term adverse
effects on the mother or newborn. Aspirin does not
increase miscarriage risk.181
Who should receive aspirin and in what dose is unclear.
Subgroup analyses in meta-analyses of aspirin trials appear
to indicate that aspirin may be more effective for women at
greatest baseline risk when it is started before 16 weeks’ gestation
and when aspirin is used at a higher dose.180,182,183
This may be because some women are more resistant than
others to the effects of aspirin,184 and/or a dose of at least
75 mg/d may be necessary to inhibit both platelet and placental
thromboxane. However, a dose of 100 mg/d may
affect fetal prostacyclin synthesis.185 One RCT found that
taking aspirin at bedtime resulted in lower BP than taking
aspirin in the morning.180,186 Aspirin may be continued until
If you want to avoid it yourself, go ahead, but anyone at higher risk of developing PIH *might* want to consider it as an option.
Very interesting. Do you live in an area that your would not get as much vit. D during the winter months? I wonder if that is affecting the calcium like you mentioned for those spring births. Hmmm...

Around here, it has become "normal" just in the past year to test almost every pregnant woman for Vit D deficiency. It wasn't heard of 2 years ago. The number of pregnant women that I have seen be deficient is huge around here (including me). Anyway, I would think that might play a big part in the winter/spring vs summer/fall baby difference.
