Hi there. Can I know whether I'm pregnant or not because yesterdayi had unprotected sex with my boyfriend. During the sex my boyfriend use his hand and inject in my vaginal but I won't feel anything. Is it possible I had pregnant because on June 15 had unprotected sex.

Yes.

So am I pregnant?

Very likely, you will have to wait till your monthly period is due, if you do not have it, wait another 14 days, (if not period) then do test, if negative, wait another week and test again.

Always use first urine of the morning when you wake up

We have no idea whether you are pregnant. You will have to wait until you miss your period before testing.
