Is there any pregnancy risk???

My girlfriend and I had sex around December 1-3, we were first grinding while fully clothed, i did not ejaculate while we were doing so, i then rolled over and put on a condom the correct way before rolling it onto the bad of my penis. We then had sex and it did not end in ejaculation. I kept the condom on until he went to the bathroom, only then i removed the condom and filled it with water to check for leaks or tears, which there were none. The following week She had her period. Is there a chance of pregnancy because of the act alone, and by receiving her period that means Shes not pregnant? 

From what you’be described, it looks like you’re in the clear. No ejaculation + condom + period post coitus are all good signs that she is not pregnant. 

You are in the clear.  If you had a condom on for intercourse and then she had her period then it all seems fine.  Can I ask how old you are?  You come across as only rather young and I was wondering if there was anyone that is close to you that you may be able to have a chat to about these kinds of things.  It is always nice to have someone that you can rely on and get some tips on small matters.
