I NEED HELP

So I’m currently on the combination pill Larissia and started on December 22nd and I have never missed a pill and take it at the exact same time everyday. So on February 16TH (which was the last day of my period). my boyfriend and I did some stuff but we didn’t have sex. He grinded on my vagina but he had tight underwear on and there was no cum but I’m not sure if there was any pre cum on the underwear. there was any pre cum on the underwear. I also sat in the shaft of his penis with us both not having clothes but for only 5 seconds and he didn’t have ejaculate on it. After that I went to the bathroom and wiped carefully to make sure there was nothing. On my app it says my supposed ovulation week started on the 18th and my ovulation day was on the 23rd even though I take the pill everyday. Should I be okay?
