Am I pregnant 🤰🏽???

OK so I have a dilemma, I am two months late on my period, now obviously one would think ok you might be pregnant, but here's the kicker, last time I have sex was on April 15 two weeks later I got my regular period And then may came and got my period everything the same everything ok, then june, no period still haven't had sex since April 15. Ok well I am very irregular on my period so I didn't worry about it. So now we're at the end of July still no period. Is it possible to be pregnant. Even after having 2 normal heavy flow periods. Now I have a son, I remember having morning sickness with him even before my first missed period and my second I had morning sickness at 5 weeks. So I did the calculations and if I am pregnant I would be eight weeks almost 9, I have no pregnancy symptoms no morning sickness no nothing. I'm just confused, wonder if any of you have gone threw something similar? I guess the only way to find out is to go to the doctors huh?😬
