Can pregancy occur if the sperm gets in the vagina with the finger?

Me and my partner always use a condom he never cam inside me even when the condom on, he always cum over my chest and my stomach. One day I decided to take the cum off my stomach with my finger and place it either inside or very close to my vagina I really can’t remeber exactly where.anyways a few days later I came on my period. However after my period I started having a nausauated feeling in my stoomach. I told him that I should take a test and he got mad and said that this was my 3rd time doing this. The other two times was false. And he got really mad and said that he aint neva having sex with me again because im uneducated about mybody, everytime we have a problem he always say that he don’t wanna have sex with me anymore and when I start getting over him he wanna have sex again, we been going through this for 2 years now and it hurting me emotionally cause it like he wanna have sex and he don’t wanna have sex, we not even a couple he was my first and only and im in love with him but he don’t feel the same way but he still care. Well anyway maybe iam uneducated bout my body but the first two time I didn’t feel this nausated and I aint neva put the sperm inside my vagina until now. Is it possible that I could be pregnant?
