Hi, I'm 18 years old. My boyfriend and I aren't very sexual, but we did have sex once with a condom, we do other stuff but not sex. I am about a week late with my period. I took a hpt and it came back negative. I thought I was getting my period but I guess it turned out to be spotting. It wasn't brown it was red. I have also been having cramps lately too. I was wondering if anyone knew anything. Id really love it if someone could help.
