Maybe ttc?

I had to do some traveling to visit family and my SO stayed back. While I was gone I decided to tell my SO I wanted to start settling down and if he didn’t want that then uk the rest. He said he did and I told him I wanted kids if my own bc I miscarried 2 in a previous relationship some years ago…and he has one already. He said he wanted the same. So when I got back home and we were having sex he came in me and didn’t say anything about a plan b or anything I just asked him if he came and he said he been came. Then he did it again the next day. He pulled out today…tmi anyways my fertile window begins in a day and ig im just confused on if we’re ttc…thoughts?
