Hcg

I’m 4 weeks and 3 days pregnant with baby #3. I had a miscarriage before my second child and kinda nervous I’ll miscarry this one. My hcg numbers aren’t increasing as fast as my doctors would like going for another blood draw in a week. My progesterone is good though. I get queasy here and there but nothing major. Is there still hope that this baby will stick u think? 😣
