Can sex harm implantation ?

Hi ladies in the cycle which I had a chemical I had sex on implantation day, well I’m guessing it is because after sex I bled and the next day I tested and got a faint positive- but the bleeding didn’t stop and then line went away :( I was (9DPO) based off opks , my question is can having sex during implantation effect the baby sticking? My husband wants to get it on but I’m 9DPO today I’m scared 🥺
