Period late after surgery?

Hannah
I had a breast augmentation just under 2 weeks ago. My period is a couple days late. I'm usually pretty regular and I get cramps a couple days before I start my period. I haven't had any yet. Also, there is no chance I could be pregnant so that isn't a worry. I am wondering if the anesthesia/pain meds/antibiotics could have messed with my cycle. I'm not too worried about it being a couple days late, just wondered if any of you guys had experienced this? Thanks!
