SCARED!!!!!!!!!

I am very scared... My bf and I are both 25 with 2 kids, we want a 3rd but it's not the right time. We have been extra cautious with protection and our main protection has been absence! well it has been about a month since we had sex and last night it got heated and normally I go for the condoms right away but it was just soo good that it slipped my mind for a min. I got ontop and started riding we both got up there real quick and I ended up "going" he tapped my leg when I got off I asked if he went and he said "Yes" I asked if that tapping was a warning or if it was because he was enjoying it and he said it was a warning. He said he was fine till I told him I was going and he couldn't hold it!! I got cleaned up, went to log my stuff in on this app and realized I'm suppose to be "ovulating" which this app has always been wrong; but yesterday was my highest chance of getting pregnant. He says if I end up pregnant we can't have another but I don't believe in abortion so I told him we'd figure it out! I'm really nervous my period has been on the 1st of every month and I don't have the 50 for the morning after pill right now😧 We fucked up I have no one to talk to but you guys and idk how to handle it!!
