Pregnancy questions

For those who are confirmed pregnant, what does an early pregnancy belly feel like? I’m asking this because I did a dumb thing that I regret with my boyfriend (yes I’ve posted about this situation before I just have a ton of questions, so sorry for the spam)he quickly stuck it in took it out and then put it away, I got my period 7 days after (that lasted a full week and was heavy) I don’t recall any symptoms of early pregnancy and I’m supposed to start my period within then next day to 3 days but I was playing with my stomach muscles and noticed my lower abdomen was a little bit higher then the part right above my boobs, is this normal?
