Confused

So we been trying to get pregnant for the longest while I started using opks this month and realised that the apps are slightly off with when I'm most fertile.. So I had sex Tues and Wednesday when my opk said negative today it was positive but we were having make up sex as we had a fight wednesday nigh and he kept pulling out today as to not cum fast (tmi) and after doing this about three to four times the fourth time he ended on me and not IN me.. I'm so confused as to why he'd choose to do this today of all days. Maybe i should have tested before having sex.. I'm so bummed out by this.. Should I try tomorrow. I'm not sure he's up for another round tonight.. We kinda burned some good energy being mad at one another.. Advise please?
