Pregnancy without Penetration. Pregnant?

I'm a 24 yo female. I'm not a sexually active person, this August 19, I got intimate with my partner, we didn't have sex, but there was some rubbing involved. 29th July was my last period date, I got vaccinated around the end of August. I got my periods on 3rd Sept at a gap of 35 days which is normal for me. I usually don't bleed much on day 1 but I did and the second day is actually the day I experience heavy bleeding but this time it was light bleeding, filled up one pad. And then no bleeding or any other kind of discharge that usually happens. After my periods I started experiencing cramps and some achiness in my breasts. My abdomen looks bloated and it feels tight, same with my breasts. Also, I'm experiencing a vaginal discharge, but I think that's normal. Recently, I started working out. I am also facing acid reflux symptoms, including Nausea. And also, I've been urinating frequently, but, I've increased my water consumption Could it be that I'm pregnant?
