I've been sexually active for 2 years now and my periods have neva been on the correct date but always been in that calculated week however last month my boyfriend and I had sex and did use a condom however before we foold around and we didn't use a condom last month I got my period 6 days late and now this month I have also been sexually active using birth control such as condoms and we are sure that they didn't tear break or slip. I also have been under a lot of stress and haven't been eating as much during the day. My period is now 2 weeks late. I've been getting abdominal cramps like I'm about to get my period and sometimes it feels like my period has come however when I go to check I find brown gooey discharge which only happened twice. I don't no whether I should wait longer or go and take a pregnancy test if anyone has any answers to my questions or knows about any of my symptoms reply your help is much needed thanxx

Stress can mess about with your period cycle, even not eating regularly can.

How about visiting your gynea, go for a check up an dits probably wise you ask to go on the birth control pill, which OK isn't 100% safe but it's the safest birth control.
