My period is seven days late. I have taken four pregnancy test and all of them are negative. I have been spotting every month for like five days for the past three months. I had sex one night and I bleed everywhere. There was a lot of blood. I thought I got my period but after an hour the bleeding stopped. Now after sex there is brown blood just spotting but nothing more. Has anyone ever had this problem? I feel like it could be something serious 😬😬
