HELP ME PLEASE!

Hi everybody I’m on microgestine fe 1/20 and this is my second month on it. Last Saturday on 1/27/18 I had raw sex. I never missed a pill or anything like that for that month but I was late or early in taking it by 40-120 minutes everyday. I’ve always had a regular period extremely heavy for 7 days for the past 7 Years. This last week my period was late by two days which was two days after we had sex and I then realized that the color was brown right off the bat the way it looks towards the ending of your period. My period lasted two days and then stopped completely for another two days and then today I had spotting once. The night I had sex he pulled out but then shortly reinserted himself in me for round two an hour later without peeing. I then was in the shower and I was checking my cervical opening and realized it was abnormally soft and raised. Do you guys think I may be pregnant??
