if anyone has experienced this with ovulating.. I should be ovulating soon.. and today I got really nauseated and felt soo sick that I ALMOST vomited and than fianlly went to the bathroom and noticed a little blood in my cm.. Does anyone know or have gone through the not feeling so great when Ovulating?? I still am not feeling to great which is making me miss my hubbys game tonight =( and I just took an opk and so far its a negitive. I normally ovulate on cd 12 or cd 13... any ideas??? or am I just crazy! lol
