Am I pregnant?

I've been on BC for 4 years. And the first few years were a little rocky and irregular period wise, because I was still trying to find the right medication to help it. For ab a year my period has been regular, but a little over 2 months ago I missed my period. Completely. No spotting, no faint blood when wiping. That's never happened before, it would usually come a few days after or be really light bleeding. I got a couple tests after 3 or so weeks of it not coming and they said negative. I also went to the doctor for my stomach because I've been dealing with constant nausea and throwing up for almost a year. And they took a urine sample, it also came back negative. But now I'm 72 days late on my last two periods. My last one was in January. I've been feeling a little bloated, nauseous and emotional, but I don't know if I'm pregnant. I would love to be, I'm just surprised I haven't gotten pregnant sooner. Any advice?? Thank you in advance 💖
