Ok, so I used a conception date predictor online and according to when I got pregnant with my son, I estimated when I ovulated. I'm supposed to this time based on that calculation on May 5th, today is the 3rd. The opk I have still shows negative, is it possible that I am going to ovulate later? I had semi irregular periods before, ie the day one ended the next started on or around that day. But I started b/c in Jan and got off Mar 29th. So I'm wondering if I will ovulate later, or could my opks be saying neg when I really am, I've been having slight cramping on my left side the last two days...
An ovulation calculator is a good way to get an estimate of ovulation, but as you know, it won't be exact. If you enter the average length of your cycle, it's basically going to count back about 14 days from the end of your cycle and give you a window around that time when you shoudl ovulate. A lot of women though don't follow this exact pattern, so the predictor could definitely be off for you. If you feel ovulation pains or have any other O indicators, you should go with that instead of what the calculator says. Have you used OPK's before? What about BBT charting? If you're just getting back to normal after b/c then these would be two great ways to try to figure out your cycles. In the meantime, if you BD every other day or so during the middle of your cycle, that should really give you a great chance. Good luck! :)
for 4 hours to get a more accurate prediction. When you get a + OPK it means you may ovulate anywhere from 12-24 hours (you don't always ovulate when you get a +. The only way to test if you have ovulated is to take your temp everyday). If you take it at 7am and it says neg you may actually ovulate before 7am the next day meaning you will get another neg.
I've decided I'm just going to BD...not even bother with the opks...that way no matter when I do ovulate, I've already BD or am going to BD that day or the next, is it better to only BD every other day or everyday?
