Pls help i'm nervous!!

The 4th of July i was over at my SO's house and to avoid sex I offer dry humping. I know it can't get you pregnant. (Unless you have certain circumstances) but in my case, we were both in under wear and i also had a panty liner on. After we finished i felt my panties to see if they were dry and they were, so i know his precum didn't soak through my underwear. If it did it wouldn't have gone through the bottom of my liner....

my period is late (supposed to start yesterday). I have been having my periods late for the past couple cycle due to a diet. I just need positive reassurance that my dry humping session didn't get me pregnant and it could be my diet or stress. Even if i were pregnant, could i feel symptoms of pregnancy by now??

Edit: 12 days before my period was supposed come i had some bleeding for 3 days. It was really light. But its normal for me because I always usually have bleeding 14-10 days before my period.

Also this past week i have experienced crippling cramps, which have eased up. I still get cramps but they are super light.

Lastly the past two days i have been wearing tampons just in case and every time i changed them i saw some blood on them.

I also have been taking vitamin c supplements to try jumpstart my period (since yesterday)

But there was blood on my tampons before vitamin c.

Thank you all😊
