A few weeks ago I was with a male partner and things started getting a little heavy. We didn't engage in penile/vaginal penetration but grinded with our clothes off, even underwear. I don't think any ejaculate got near my vagina (I don't believe he ejaculated at all) but I'm 2 weeks late on my period now and I'm very concerned. I took two pregnancy tests which were negative but still haven't gotten my period. I typically run irregular on my periods, but the last few months have been fairly consistent.
I noticed some nausea this week (no vomiting) and fatigue, but that could be from my diet. My poor diet and stress may have delayed my period but I'm unsure. What's the likelihood of pregnancy without ejaculation into my vagina? Also, I'm a virgin and I've never been penetrated.. I may be over reacting, I really hope so please help!
