Pregnant? Long story

Okay so. Me and my SO have done it multiple times since my last period, which is new for me. Its my first time having sex a lot, so maybe my vagina is just trying to get used to it. Ive been having normal period symptoms for awhile now. My period is normally always irregular, so i never really know when its going to come, but i believe that im at least a few days late. The last time me and my man had sex, the condom broke in the middle of it, and he wasnt even close to finishing. He said i should be fine, but thats the only really time that i could get pregnant. That was near my ovulation, so thats a factor as well. The condom broke on Nov 25th, and last month, my period was the 24th-30th. Is there a risk for pregnancy?
