Okay we'll I have a lot to ask and say let me start off with I do have unprotected sex with my boyfriend , my periods are usually heavy very heavy !!! This time it was very very light spotting it was pink at first then brown then by the end of night red , the next day it was heavier by middle of the day even heavier next day it was like a actual period ! At first I thought it was implantation I've read a lot of diff things on it a it is not normal to have a heavy implantation bleeding so then I was thinking it could have been a early miscarriage or something we're u can get pregnant in your tubes or something ? Before I started my period I was having pg symptoms such as really tired , sick and some what emotional , sorry for the long message anyways so it's been about 2 weeks since then maybe 3 and I haven't been worried about it b.c maybe it was just a weird period , but my stomach looks to be getting a slight bit bigger i don't know it's only 3 weeks it would even get bigger maybe I'm just thinking to much but my nipples are also getting a tiny bit darker , can some please just give me some advise I'm only 18 and so lost on this situation ?!?!
