I have been trying to get pregnant for about 7 months now (after having an Implanon progesterone implant removed in May). I have always have irregular cycles and while the implant was fitted I had periods every 2 weeks most of the time. I have now calculated my average cycle at 35 days and my latest cycle was indeed 35 days exactly. My cycle has known to be as short as 28 days and as long as 42!
According to Ovulation calculators I should have started my latest ovulation tests on the 1st of December. My concern is that I did not get a positive result from the the tests until the 12th of December and my latest period arrived on the 18th of December. If I am ovulating this close to my period/ this late in my cycle will I have trouble conceiving?
If you do have a short luteal cycle, the problem is not conception as much as carrying the pregnancy after that. The fetus needs time to "plant" and get situated before it is time for a period. Some women need some extra progesterone to prolong the pregnancy until it "sticks." That said, at times the ovulation kits can be off a little. You might want to invest in a good fertility consultant to review all your records and make suggestions. Good luck!
