Different period after losing virginity?

[Klarkins]

I lost my virginity to my boyfriend of a year back in april and 2 weeks later my period came 3 days earlier but it wasn't like they used to be. I spotted at first then it picked up but it was really light then it was mediumvfor 2 days where I only filled up one pad a day then got light again for 2. My periods are normally heavy so this raised alarm for me being pregnant. We used a condom but for the first couple of strokes I let him put it in to see if I wanted to keep going (TMI). I heard about precum and thats whats been freaking me out. I got another period on time and it almost like the other period but the cramps were extreme the first day. I took 5 hpts and 1 with a doctor but im still freaking out. I feel like I keep giving myself symptoms like nausea and I always think I have to pee so I keep going. I just want to know if anyone has had weird periods after losing their virginity and if this is normal for your period to change?

Hello.  Our hormones can shift and our periods can change.  It happens and will continue to happen throughout your adult life.  It is really unlikely you got pregnant with this but since you did allow him inside your vagina without a condom, that is a risk.  A penis emits small bits of sperm in these instances.  It 'can' be enough.  Again, I do really doubt it but if it happened 2.5 weeks ago, you can take a test to be sure.  If you continue to have irregular periods, see your doctor for a routine pelvic exam.  It might be a good time to consider the pill then as it will not only protect you from pregnancy but regulate your period.  good luck
