Early pregnancy or pms?!

I've been having minor symptoms for a little while now but tonight's been so weird. About a week ago I went to the ER for hives all over and having a hard time getting in enough air. They tested for pregnancy and it was negative. But tonight I've been peeing constantly!!! Its not burning or anything so I know it's not a uti. And then I was watching TV and started bawling...multiple times. Then my boyfriend made a pizza and I got so nauseous. It smelt terrible and I couldn't eat it. Ive also been freezing all day. My boobs have been hurting and I'm breaking out like crazy too. I know these are all pregnancy symptoms but I just have such a hard time believing it and I'm so scared my periods gonna show up because I've been having cramps off and on...my boyfriend said we can get a test in the morning and I'm so scared to test I dont wanna be let down again...
