Hi all need advice

I had my colcoscopy the end of Jan then I ended up having the LLETZ procedure done in March which I caught an infection but has cleared it's been 3 weeks Monday that I had it done seems like forever waiting for results to come back, but I've been showering since and haven't had a bath when will be the best time to have a bath as I do not want to catch another infection also when are you able to have sex after the procedure? Any help or advice would be great thanks all
