Okay, so I had unprotected sex on the 11th of august, was a little drunk, but remember him finishing on my stomach, still took a plan b on the 13th. I then got my period on the 23rd and it last for about 4 days (normal for me) I had a uti and visited the Dr. on september 3rd and took antibiotics for it. They had to test my pee just in case and it came back clean just a uti. But I can seem to calm my mind about the off chances of being pregnant. I?ve been getting cramps lately, and i?ve been constipated, and I take quite a bit of advil for headaches lately. Can?t twll if i?m just worrying my self to the point of feeling sick or if there?s a chance I can still be pregnant. I?m supposed to get my period in 10 days. I know I should take a pregnancy test, but I keep talking myself into me just being crazy and then I calm down and then something else makes me go crazy and start to think i?m pregnant again and my cramps come back. What would be your opinion?
