Multiple chemical pregnancies

Melle

Hi. I'm currently experiencing my 2nd loss in 4 months. Another chemical pregnancy/early loss according to my doctor. Got a positive pregnancy test last weekend and was so excited but when I went in for blood work Monday, the nurse was concerned because my hcg level was so low. Tested again yesterday and it's not increasing so they told me it was likely another chemical. I've been told that chemical pregnancies are common but is there anything else I can do? Should I make my doctor run some tests or anything? Had a progesterone test done before I was pregnant and it came back normal and showed I ovulated. Luteal phase is usually 15 days so I don't think it's a luteal phase defect. I'm just so confused and not sure what to do anymore. I'd love to hear any success stories available or any suggestions/advice. Thank you for listening to my rant.
