@sassenach84, fyi OPKs don’t actually tell you if you are ovulating. The measure the surge in LH (some also detect oestrogen). Those are the hormones that control ovulation, so your LH surge basically says “you are going to ovulate in the next 12 to 18 hours, so your fertile window is the next 4ish days. BUT they don’t tell you if your body is able to respond to the LH surge by actually releasing an egg.
(I’m not trying to be negative, but there is a big misconception that OPKs can tell you if you have fertility problems, and I think some people delay going to a doctor because they think they are ovulating regularly because they have a regular cycle and get positive OPKs. It’s not necessarily the case e.g. if you have damage to an ovary or a blocked Fallopian tube. The tests your doctors will do will include measuring progesterone, which can tell you if you are ovulating. Doctors measure progesterone, which the egg itself releases into your body, so a blood test for this CAN indicate if ovulation occurred. It’s not used by OPKs because it would give you the information AFTER your fertile window, so not helpful for ttc).
Please don’t think I’m being pessimistic, I just think it’s important to be armed with information when you go to your GP in case you get brushed off with “just relax and it’ll probably happen”. You wouldn’t be there if you hadn’t already tried that!
Rant over, sorry!
Getting fed up with long cycles. If I OVd, I’m pretty sure I know when it was and AF should have been here 2 days ago. I wish she’d just bloody hurry up so I can get onto the next cycle! (There’s no chance of a BFP this cycle, timing was all wrong and I have absolutely zero symptoms aside from PMS ones)
