Am I crazy?

So my SO and I broke up a bit ago, so it's been around a month since we've had sex, I've gotten two periods since then (one right after we broke up, was 4 days early without normal period symptoms, but normal length/heaviness) and then one recently (on time with cycle) the problem is, I'm still having pregnancy symptoms, constantly hungry/nauseous, peeing frequently, extreme exhaustion to where I fall asleep sitting up on the couch, just generally feeling like crap. But I've had 2 periods? There's no way I could be pregnant, right? I know some people experience a 'period' and still end up pregnant, but two? I've yet to take a test because I've just had too much going on, can anyone give me some advise?
