Going overboard or what ?

C`

Alright guys so I took 4 pregnancy tests and they all came out negative . I had surgery last Thursday and that’s a mandatory pregnancy test. And I started my period Friday .And if I was pregnant they would’ve told me right then and there . I’ve been on hydrocodone, an antibiotic , and ibuprofen after my surgery . My pee is slightly cloudy . I personally think it’s just dehydration because I barely eat and barely drink . Should I be worried or am I just being a drama queen? I had sex on February 11 and got my period March 8th and ended March 13th .
