We've been ttc #2 for nearly 2 years (took 18 months to get bfp which resulted in dd), we recently did our first ever fresh IVF cycle and got a bfp but had a mmc and erpc three and a half weeks ago at 8+3.I fully understand that anything lighter than the control line is negative. I also know that patience is key and mc can send your cycle a bit crazy as this isn't my first experience with it. My question is, if I was getting faint lines on the opk for about 5 days but am now getting no line at all over the last 3 days, testing twice a day, is it likely that I have already ovulated and it was just really early? I know af can be delayed after miscarriage and it wouldn't be due yet anyway but we're waiting for af so we can start our FET cycle and I was hoping opks would give me some idea when to expect it. Anyone experience anything similar?
