My boyfriend and I had last had sex on the fourteenth of February. <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> said I was supposed to get my period on the 6th of march. I didn't begin to bleed till the 10th (Friday). I took a pregnancy test that Thursday the 9th and it immediately came out negative. Although the bleeding was consistent Friday along with my usual aches and pains, it continued into Saturday but stopped halfway thru the day. I have since then not produced any more blood. It's a bit unusual for me because my period usually last three or four days max. The second day being my heaviest day, but the second day, was almost like my last day of my period. I'm confused as to whether or not i just had an abnormal period or something I should be worried about?
