Please tell me I haven't got a bug!

So today I'm 37 weeks pregnant, was having an ok evening- swollen feet and ankles as per norm.. then started to feel really nauseous and I mean really nauseous- stomach is getting BH ( I assume , they aren't hurting) so here I am after throwing up 3 times... baby still wriggling around but at two am what do I do??

I just feel like I'm in limbo...
