hook effect on HPTs

Ok, I know this is such a idiotic thing...but as I mentioned in my other post I had some cramping and bleeding. I've had lots of miscarriages before I had my children. And in all of my pregnancies I seem to have a subchorianic bleed. So that's why I'm not completely freaking out about the cramping and bleeding, but some a little concerned.

I never stopped testing. I think the reason is because I just can't believe I'm pregnant. I know I know it's like believe it already, but I never thought I would have 5 children. I never put a number on my family. I am ok with it now though in the beginning I was kinda freaking out and in denial, hence the many many preg tests. I had a bunch of the wondfos left so I just kept taking them watching the test line get increasingly darker than the control line. It got sooo much darker than the control line.

After the bleeding and cramping, I thought to test again but omg it was lighter than the control line after that. That was yesterday. So then I thought let me try again tomorrow (today) and it's still lighter!! so then I started freaking out that maybe the bleeding and cramping means that Im losing my baby.

Now I started googling and apparently there is some sort of hook effect that even makes some pregnancy tests test negative at some point. I just don't really know if I believe this or not. It's weird, but that apparently that's how women who have irregular cycles miss a few periods then test negative and then show up like..umm I've got pain in my belly and the preg tests were neg. but yet they're in labor. I don't know how much of that I believe but I guess it happens.

So in light of that long story I was wondering if anyone's more than 7 weeks and have been testing still (if you can admit it) and also have another one left to see if your test line is lighter than your control line??

I know these hormones are making me insane. Anyone up for a test of this hook effect theory?

I have heard that pregnancy test do only work up to a certain point but I can't remember why or when I heard that. I am just over 6 weeks but I will test at 7 weeks & let you know cuz I got tests. I am 6 weeks 1 day ( i think) do you want me to test now & then or only after 7 weeks? I have like 10 tests left

LOL you're awesome. I don't know. Maybe do one now to have something to compare it to next week and then the next. What do you think?

I am not getting an negative like in the link Alissa posted but it's jut lighter. I don't have a lot of tests left. I think I'm going to drive myself and everyone crazy til I can hear the heartbeat and move out of this first trimester. It is truly a crazy time for me.

Thank you Alissa for the post. I read here and there about it but I just wasn't sure if it's really true. Biggrin

Just throwing my 2cents in. A friend told me she stopped testing at 6 weeks because the tests stopped getting darker. I'm guessing it's pretty normal.

With previous losses will the doc give you an early u/s? I would ask for one just to ease my mind in your position.

i would ask if you can get your blood tested for HCG and see if it's doubling or get an early us to see the heartbeat. i wouldn't rely on pg tests alone.

Ok I'm 7 weeks & took another test. It is as dark as the last one I took. I would say it is a smidge darker than the control line (very deap red/pink).

So what's up with you now? How are you feeling?

You're so cool and sweet! I was at the Dollar Tree the other day and bought 3 tests. They are super dark, slightly darker than the control line. I think maybe I just had a few in that batch with ink issues or something. I am sick sick sick. I have a new pattern of sickness where in the morning it's not that bad but in the afternoon after I eat O M G is all I can say. It's all I can do to keep from throwing up. I have found sometimes eating sugary things helps. I am ok otherwise!
