2 weeks late and 3 negative tests, not TTC

Megan

I'm usually fairly regular and have ovulation cramping every cycle but I'm 14 days late today. I've been having mild cramping on and off but no signs of period other than that...

I've taken 3 pregnancy tests over the last 2 weeks and all very negative.

We use condoms every time and he always pulls out to ensure no pregnancy.

What on earth could be going on???
