So confused as to what is going on now. I thought I had a shot last month but then I had the worst cramps ever and bled 3 days around 5th Jan. Assumed this is period and proceeded to start over for this new cycle. I've had a few really strong OPKS this week which is odd as a week before the new fertile window is predicated. I took a few pregnancy test on the offchance and they are positive! I'm now so freaking confused as the bleeding was enough to make me think a period and the cramps are the worst I've experienced for a while and over a few days. On positive test indicates 1-2 weeks but we haven't had sex since 26th dec! Does anybody know if this is chemical or what could be going on with my body? I'm reluctant to think this is real given timing makes no sense and I've had no temp rise - really don't know why these tests are picking something up.
