HELP! Am I pregnant?

Okay so I stopped taking my birth control for 2 weeks and then got freaked out and started them again.. lately I have been feeling this weird pressure in my lower abdomen where my uterus would be, the other morning I was super nauseous but it last like 5 minutes.. the other day I was dizzy all day and hot like hot flashes..I also feel slightly bloated but like I can’t flex my stomach. Also when I press down on my lower abdomen it’s sort of sore.. what does this mean?!
