Ok so I'm 16 and I got my period on the 23rd and my period only lasts 4 days since I first got my period which was about 2 years ago. It's now the 30th and since yesterday my lower back has been hurting a lot.. and the last few days my stomach has been hurting. Yesterday when I woke up I felt really sick like puking but I didn't. I've been getting a weird kind of discharge that Ive never got before.. it's like brownish orange and slimy.. and yesterday when I went pee 2 small chunks came out with a little bit of blood.. hardly any though.. today I have more discharge in my underwear and when I wipe. My boyfriend and I DON'T use condoms but he pulls out. I'm not sure if this has anything to do with pregnancy because I got my period but I'm curious of what it is. I talked to my boyfriend about it and he said we should go to the doctor tomorrow and I should get checked out, but I'm really curios right now. Please help!
