My husband ejaculated inside me twice on a saturday(6th) and once the next day (aka three times). My period trackers says that I ovulated on the 3rd but that is only because my last period was irregular and came early, normally I would have ovulated on the 6th.

I have been feeling my uterus slightly twitch which isn't normal for me but I keep thinking maybe my period is just coming early again. I am supposedly going to get it on the 17th. I know there is no real way to tell until I miss my period but I would like to know the chances of pregnancy?
