help? pregnant?

so i need girls advice and thoughts and help on this!! might be tmi, but here goes. on the 16th august my boyfriend and i had protected sex for the first time (both were virgins) and i wasn’t worried because i got my period on the 19th, when it was expected....when it ended my boyfriend and i did things, but didn’t have sex again. he fingered me, i wanked him off etc, i didn’t think about it at the time but i realised that may have pre-cum or even cum, got it on his fingers somehow and then fingered me. we had sex (with a condom) again on the 29th but i didn’t think much of any of it til i got a thick white discharge today (4th september). it might just be me being paranoid, but could i be pregnant? i guess i might just have to see when my period comes in a couple weeks x
