I am 22 years old. I have pcos detected in my ultrasound. I had heavy periods after missing one period which continued for a month n stopped after taking regestrone. I was close with my friend before my periods missed. We were in our undergarments and very close to each other but the whole time we dint remove our clothes and he also dint ejaculate. Is there any possibility of me being pregnant? Am I pregnant? I did not have any pregnant symptoms. Is it due to hormonal imbalance? I also had a 2 day spotting before start of my periods, which usually come.
