Really need advice/help

My periods have always been regular and on time. But it's currently 2 days late. I'm now 14 dpo. Had cramps mainly on the right side since 12 dpo but today I don't have any. Had tender breasts and nipples for 5 days now, I've been feeling more bloated a gassy. Felt nauseous ever since 12 dpo but not felt neaseous today. Done several HPTs and all were bfn.

I'm getting really frustrated I just want to know if I'm pregnant or if my periods just late which will be the first time.

Anyone got any idea what it might be?
