Possibly pregnant.possibly

I'm a 22 year old male from puerto rico. These recent months have been horrible in my life and my mental stability has been a huge roller coaster ride that now appears to be at the highest peak before the steepest fall. I recently got back together with the love of my life, a beautiful woman who I adore worship and love with all my heart, when we got back this brought peace and tranquility back to my life and mind, however, before this in our time apart I had a thing with a friend and now she tells me after a month that when she first told me she was pregnant and then she wasn't, well now she says she still doesn't even know for sure. We had intercourse two days before her period was supposed to arrive. She has supposedly taken two OTC wallgreens pregnancy tests that both came back NEGATIVE.

This girl I feel absolutely nothing for and I'm sure I never will and she knows it more then anyone else however I get the feeling that I can't be sure as to trusting her because she's ignorant and has a thing for me that I believe could actually make her create this entire scenario to destroy my relationship, if in fact it is true well then I would obviously step up to my responsibilities with the child...but what I'm in dire need of is someone to help me get through this the right way and not lose the only person in my life I have ever truly wanted a future and family with. Thank you for taking your time and in advance I thank you for your support. I'm not a perfect person, nothing close to it, I know it wouldn't be easy but it would be near impossible to get through anything without a heart...
