Had a withdrawal bleed from the pill on the 19th-23rd December. After a long wait finally got my af on the 4th Feb-8th Feb (48 day cycle). Now I am on cd 33 and no af, all poas bfn. I think I have completely miscalculated and missed out on my fertile time also. What do I do if my cycle is 40+ days again? Should I seek advise or just wait and see it it settles? When would my fertile period have been this month? The ovia app has now completely gone into meltdown after my predicted period was not when it said it would be and I'm guessing as result of that it predicted an incorrect fertile time too. Any ideas?
