Hey all, before I start I'm sorry if I'm being a bit gross, just worried. So last night me and my boyfriend had sex and after there was some blood on the sheets but when I went to the toilet there was nothing there so thought it wasn't me. But we had sex again this morning and when I went to the toilet there was blood in my underwear and I have been bleeding since. It seems like I'm having a period but I stopped my last one last Wednesday and ain't due again for another 3weeks. I have some pains in my stomach today as well and my back. I'm not on contraception and haven't been using protection so I'm not sure if I'm pregnant. I done a pregnancy test before my last period because it was 6days later but it was negative and then of course I got my period which I forgot to add only lasted 3 days. I know that's a lot of mumble jumble information but can anyone give me some advice, please. Thank you x
