Scared I might be pregnant

I had unprotected sex with my s/o around 3 days before my expected ovulation date as per the app. Pulled out way ahead of time and I know precum can potentially have viable sperm cells. I’m due my period in 6 days but I’ve been having mild cramps all day today and yesterday. Breasts were a little sore most of last week and today had some very little spotting but it stopped. Also I’ve been really dry in terms of the CM. I know that’s not an indicator of anything but I usually go very dry just before my period starts. Im really scared that’s possibly implantation bleeding?

Has anyone else had a similar experience before and was it just period symptoms at the end?? Just want someone to put my mind at ease please. Really praying to God it’s just PMS and I will eventually get my period 😭😭
