Kind of worried

I’m expecting my rainbow baby I have had 3 miscarriages in the the past two years my hcg levels are rising very slow and my ob won’t answer me about checking my progesterone my levels were only 16 last Wednesday and got rechecked yesterday and they are at 297 I feel like they should be higher anyone else have low rising hcg and everything turn out just fine?? I’m really scared I mean I’m still having my normal pregnancy symptoms and I’ve been taking baby aspirin once a day and all of the other vitamins that I need to take
