Hello, three days ago my husband and I had unprotected sex, I am not trying to actually get pregnant but we are not worried about it. But two days ago, I startred noticing mucus like gel that was very clear after I used the restroom, I have never had that happen a day after having sex. Day three, I have now spotted redish brown blood and I am having such a bad head ache, what is the cause of this? My concern with this whole thing is, I wasn't due to start my period for another 2 weeks, can you possibliy help me out?
