Hi everyone! Please help! So I have been using OPKs this month for the first time. I haven't started tracking my BBT but I might have to. Yesterday I woke up (CD12) and had a light brown spotting with EWCM on the toilet paper. I have had pressure on my right side (ovulation pain) since Sunday and my BBs are tender. Today my CM is watery and the pressure is almost non-existent. As I said before, I have been using the OPKs but have still not seen a +... I have read a few places that sometimes OPKs dont work for some women? I have been using the first response 20 pk. Is there any chance I ovulated yesterday and 3 OPKs didnt pick it up? All that has been showing up on the test strip is the control line. I read that spotting is a good sign of fertility and is related to the follicles rupturing to release the egg...if that is the case then wouldn't the day I bled be the day that I ovulated? PLEASE HELP!!! TIA!
