I am a TOTAL OPK novice so I apologise if this is a really dumb question, but.... I've been using the ovulation strips this month and yesterday had two dark lines. I'm not convinced the test strip was darker than the control strip and they both looked thin so I was worried the dye had run, but we did the BD anyway. So, today was a definite negative and the test strip was the lightest it has been in a few days. However, just now I noticed stretchy CM so we BD again. If yesterday was truly a positive, should there have been stretchy CM yesterday instead of today? I'm SO confused! Does it sound like I could ovulate? I thought maybe it was leftover swimmers from last night but it seemed very different. It's my first cycle since having LO 16 months ago and I have an appointment with a fertility clinic on Wednesday so I'm just giving it the best shot I can I also have PCOS and have zero experience of what a *normal* cycle should look like.
