I had sex on April 11 but we used a condom but I’m not sure if he pulled out or not. Since then I’m pretty sure I had a period but then around may 15 I thought it was my period but it was only 3 days which has never happened to me but I don’t think it was spotting because it was pretty heavy. I’ve taken a test and it came out negative but for about a week or so now I’ve been feeling nauseous all day, along with cramping sometimes, and I was spotting a few days ago. But yesterday I bled enough to bleed out of my tampon. Does this sound like pregnancy ?
