We are TTC no 2. Not easy as my cycles are all over the place ranging from 26-46 days. This cycle I have been doing an OPK at least once a day since day 9 and no positive result, yet today (day 31) my AF started. So how the heck can I be having a period when according to the OPK's I haven't even ovulated??? I am seriously confused, not to mention frustrated given that I have not been well and in a lot of pain the last two weeks but have been doing the deed regularly just in case I ovulated, yet it's been futile.
