I had my last period in April 24th, and maybe about 5 days ago I thought I was starting my period again...but it only last for about a couple of hours (not even half the day)...I still haven't bled since, I'm having abdominal cramps and I have been hacking up spit (sorry) for the past week or so....pregnant or ovulating? I'm not sure, I did take a home preg test but it came out negative...too early to tell?
