what's going on.

So I'm currently 4 weeks pregnant with my rainbow baby (2 previous miscarriages) and tbh, i feel miserable 😩 I've been nauseous, can't eat or drink anything, everything stinks, I'm tired and exhausted ALL the time, I have reoccurring headaches, constipation, and I'm bloated beyond belief. Well now my stomach feels tight... why is so much going on, I've never had anything like this
