My last period started on 17th October 2016. On the third day and 4th day i had sex with my boyfriend. we use condom. After that i took i pill for more precaution. One week after intercourse for 5 days i had very light brown spotting . My cycle range between 32-35 days since last 5 months. So i am supposed to get my period on 20th November. But since last night..i am having cramps..abdominal discomfort..and brown spotting.Do you think i am pregnant i am very scared.
