Can chlamidya affect periods?

Hi ladies so recently been slightly wild after coming out of a mentally abusive 3 year relationship. I hooked up with this guy who I’ve known for years just for some fun.

Since being single he is the only man I’ve slept with. I first slept with him 6 weeks ago. Well I’m 9 days late for AF. Negative hpts I’ve ordered a chlamidya test to be done. I don’t have any symptoms just very wet CM (no smell or itchy) and lower back ache (what I normally feel like when AF comes).

Should I be worried? And for anyone who has had an sti did it stop your periods?
