Is it possible to get OPK + after ovulation? FF is confusing me! Also question about migraine med
So I've been charting my temps now for the past 3 months and I have to say, from my experience, Fertility Friend has been off each time by a day of when I ovulate. But this month it's really confusing me! I had 2 1/2 days of + OPK but prior to the + OPK's, my temp dropped a lot. On CD9, my temp was 97.5. That day, my CM was sticky and glue like, I also had a sore throat and a cold started that day. I took 2 Benadryls to help me sleep through the night well. The following morning (CD10), my temp dropped to 96.9. I never hit the 96's. Usually stay around the 97's prior to ovulation. Then on CD11, my temp was 97.93. Fertility Friend is saying it thinks I ovulated on CD 10. However, I did not get positive OPK's until CD11, CD12 and first half of CD13. I'm a terrible migraine sufferer when my hormones change and I did get my usual extremely painful migraine on CD14. I believe when my progesterone levels raise, this is when my migraine comes on. So I woke on CD14 with a temp of 98.18. So these were my temps, would you agree with FF that I ovulated on CD10 and also, is it possible to ovulate and then get 2 1/2 days afterwards of positive opk's?
CD9: 97.5
CD10: 96.79 (took Benadryl night before and have cold and sore throat)
CD11: 97.93
CD12: 97.92
CD13: 98.26
CD14: 98.18 (felt migraine coming on this day; usually means ovulation has taken place or will be)
CD15: 98.21
CD16: 98.33
CD17: 98.08
CD18: 97.77 (rough night sleep b/c son is getting 2 year molars so was awake part of night)
CD19: 98.4
Any help is appreciated. I'm so mad at myself lately b/c I've been terrible on the diet between the holidays and not being able to skip breakfast due to stress. I'm in the 2ww now and if I end up with a boy, it's understandable; not that I would be upset with a boy but a little girl would be nice to have around the house and family.
Also, does anyone know if Fioricet sways? It's a combination of butabital, acetaminophen and caffeine (not the one with codeine, the pill without it.) It seems I have to take 2 of these when I get the crazy migraine around ovulation.
Thanks in advance for your help. Appreciate it.
