Whos the babys father??? might need a DNA....?

Ok i'm currently 8 months pregnant but 2 guys could be the father. Guy #1 the last time I had with him was in August, then I got my period in september but u can still get your period when you're pregnant. Guy #2 i had with in October and the next month i was confirmed pregnant. which guy do u think is the dad? please dont call me a tramp or anything cause Guy #1 we used a condom but when we were done he put his in me a little bit hwne he took the condom off and i know that sperm was still on his .
