Kind of worried

So my period generally lasts for around 5/6 days, but this time round it's only lasted for 3. The first day was a light/ moderate flow, second was pretty heavy with clots and the third day was just light/ moderate with a few clots. The last time I had sex was the 30th of June, and that was unprotected (stupid decision) and around 5 days before predicted ovulation, but he didn't finish. I know I keep spamming the community and I'm really sorry, but I'm kinda worried. Please no hate 😕😕
