I had unprotected sex on the 8th of May and my period was supposed to start on the 14th but it never arrived, My partner and I have been trying for about 1 year and still no luck but I am now 9 days late and I am very confused, we had unprotected sex again 2 days ago and after I went to the bathroom I noticed I had blood, it was red with mucous but after that I didn't bleed again so I'm not sure if those two situations are related or not. I just really don't know what it could be and I hope I am pregnant but again I have no clue as my period is also not always a 28 day in between, it can vary from 27 to 35. I hope I can get some help! Also I am in my 20's if that helps as well.
