Am I pregnant?

I had sex without using any preservatives with my partner when I was fertil but he did not ejaculated in the vigana, he ejaculated in my pelvis near it. 
Perhaps he never pulled off until the ejaculation. It's been almost a month since that and I'm experiencing some unusual things like abdominal pain, nauseas, I feel tired all the time, some times I feel dizzy and I'm bloated.
​On Friday I'm supposed to get my period, but I'm really anxious.
​How am I going to tell my partner if I'm pregnant?
​My body is telling me something?
​Are this real symptoms?
