Ok so I lost my virginity on April 2nd (a couple weeks ago) we used condoms but he changed it twice when we had sex so if the condom broke my boyfriend didnt tell me cause I ve been feeling fine up until April 10th when I started having abdominal pain and I ve been experiencing a bit of heartburn and feeling nauseous, some constipation and frequently urinating, my stomach would be warmer than normal, and a few other things, now im scared I might be pregnant. I took 2 pregnancy tests April 11th at home but they came back negative and I was told it could be too soon to tell but im still feeling these pains and all, could I be pregnant??? Please help. Btw my periods are irregular so I can go months without a period but my last period ended March 30, the week we had sex.
