Well lets see I dont know how to start out im 16 and sexually active. Around the middle of febuary I believe I slept with a guy. He was not using protection and i'm not sure if he came in me or not... Yes stupid mistake I know .....But I guess thats what alcohol does to you...Anyways probably about 2 weeks later I took a pregnancy test it was negative. I've also been having a lot of stomach problems such as abodominal cramping and bloating. Monday I was sexual active and monday night I was very ill and probably about 3am I went to the bathroom and it hurt to pee and probably after 10 mins I realized I was bleeding but it was hurting very badly when it came out. So I told my grandmother who is an rn and she told me to take an advil and drink lots of water for now till tuesday morning. Well we called the doctors yesturday and set up an appointment they believe I have a bladder infection..Could it be a miscarriage? I've been bleeding heavily and having a lot of cramps... Also theres traces of blood in my urine....So today I will going to the doctors but I was just wondering what any of you guys think of this... Thanks..
