puttinga condom on; pregancy question

okay well im 16 and me and my gf decided we were going to have sex and we fooled around a little before having sex. I had a little premature ejaculation at the tip and i took a tissue and wipe it off. I then putted the condom on and it was faulty. I i tried another one and it wouldn't go down all the way. I tried another one and the same thing. I putted a fourth one on and it work but before putting it on i was my pelvis and my penis with soap and water. We had sex and i pulled out while i was cumming. But more or less before i was cumming i think. I just want to know the odds of my gf being pregnant. Also i used spermicide condom. My gf gets her period between the 4-12 and we had sex on the 18th. Thank you for helping
