Is it possible?

Kathryn • Hello everyone, my name is Kathryn and my fiancé and I are trying for baby number 2. We have a 4 year old daughter
Okay so can I ask a question? Please don't laugh but my fiancé and I have had sex the past two nights and both nights he says he has cum but here is the thing..I always know at least 99% of the time if he cum cause the next day I have discharge. Yesterday I had none and today nothing. I had some clear stuff but today is my ovulation day. Can guys really fake cumming or stop themselves? I don't get why he would. We don't have any issues. Our relationship is great. He wants another baby. The only thing I can think of is if we got pregnant this month we would be due around time of our daughter birthday and I know he wanted some distance between but at this point we've been struggling so I just want a baby lol..anyways is it possible??
