My last period was Aug 25th. Since then I've been feeling fine. Oct 3rd & 4th I got slight cramps with very little brown/pinkish blood and haven't had that since. (Before bed on the 4th I felt very nauseous!!) I'm just wondering if I ovulated late and that was IB?? I'm so lost bescause I've tested 3 times and BFN. Helppp!
