Confused...

So my last period was on March 2nd, I haven’t had one since not even cramps, spotting, literally nothing. I actually didn’t even realize I hadn’t one until the end of April all I tested probably 1 1/2 weeks all regular lined test and digital both were negative/not pregnant.

I woke up 6am in sweats bad (never happens I sleep with fans and a/c on) I got a little nauseous. Fast forward to 8am woke up again and had to run so fast to the bathroom I threw up everywhere and I threw up multiple times. I had slight cramp on my lower left side when moving off of my stomach and in my head I was thinking well shit your smashing the baby lol (jk jk).

Should I go out and buy more tests? Im very high risk immune system so I won’t be making any doctor appts until I know.

TIA 💋✌🏼
