I'm eighteen years old and three weeks ago I came off a three week period. I was wondering when I can expect my next period and I am also a little worried because the period was so light - basically just wore pantyliners and lites the whole time. I am having sex but we use a condom and since we once had a pregnancy scare we have been very careful about spillage and safe sex. I was on the pill briefly but, as I am also having problems at the moment I came off because the hormones were making it worse! I don't know if perhaps the strange period is stress related or hormone related but I wasn't that stressed six weeks ago. I just don't want to start panicking and making my period later by panicking!
