Ugh in laws coming

So I'm about 10-11 weeks pregnant and I am just at that time where my sense of smell is much stronger than normal. It's making me really sick, I've thrown up twice today and been nauseous for a few hours but I'm laying down on the couch trying not to throw up again.

I know I'm probably being dramatic but I got upset at my fiance because he invited his parents and brother over tonight when he knows how sick I feel.

We also aren't telling anyone I'm pregnant until I at least have my ultrasound at 12 weeks and now I don't know how I'm going to hide it because theyve been talking about us having kids so they are expecting me to be pregnant soon. ugh oh and our AC isn't working now so I'm hot and they always overstay their welcome (they will stay until literally 2am)

I just wish he would understand that I don't feel well and I'm not making shit up
