My partner and I are trying to conceive, and so Im kind of curious on some things. We had sex the other night, I then gave him a blow job which resulted in him ejaculating in my mouth, and then we proceeded to have sex again. He got kind of soft because the room was really cold and so he got upset and we stopped, he tried again and was still soft so I gave him another blow job and he got hard again so we had sex again. This time, we had full on sex for awhile until he got soft at the end again and then when he was done he didn't clean up, no bathroom breaks or anything because of the trying to conceive issue. Well, he did say he got off, but I don't know if he did inside me or just had an orgasm because of all the going soft issues.. My last period was November 9th until the 13-14, and we had sex on the 20th... that was a fertile day right? I don't know how to usually how to tell how many days my cycle is.. if anyone can help me with that and what my probability of conceiving is, thanks!

Anytime there is penile insertion there is the chance of pregnancy. Beyond that there is no way for anyone to predict the chances you will become pregnant.

You will just have to wait until your next period id about 2 weeks past due to start testing.

The general rule is that two weeks after you start your period is when you should ovulate. That is the average rule. It is really variable so your fertile days might be right at the start or end of your cycle. The best way to know is to track your basal temperature. Google that.
