Am I pregnant girls?

Rachel • I am the bipolar Queen🙋👑
Hey girlies!! I would really like some help only if you have a proper answer. My periods didn't come at all this month, I didn't even have back or stomach pain. Although my growing pains have been so intense. 
I skipped my periods last month and the month before; so maybe that is it but also, if I was pregnant, by skipping those 2 months I could be a 3 months along..  I've also been on the pill for 3 years but I am bipolar so my medications CAN interact.
