I'm starting to worry. I had sex the fourth of this month but we used protection. I was suppose to get my periood the 15 but I didn't, it was a week late. I got it the 22 but it started out brown wich is something that has never happened to me. My period blood was thick wich is something that is not regular for me. After it ended on the 28 I thought I was fine but then on the 30 I noticed some blood on the paper after I wiped myself when I used the restroom I thought it was just a little left over, but then through the day when I went to use the restroom my panties would be spotted with blood as well as the paper I used to wipe myself with. I don't know what's going on. Any information would be appreciated.
