Pregnant after mc

I had a mc back in January. I got my first VVFL Thursday. I have tested every day since (second two tests not with fmu because I keep waking up in the middle of the night to go, and I’m not going to test at 2am). I went in for bloodwork the day I got my first positive since I had a mc. HCG was only 10 (I guess these tests are super sensitive!) and progesterone was 18. I go back Monday to get more bloodwork to make sure my numbers are rising. I have very irregular periods, so there’s no way of knowing how many DPO I am. I’m trying not to be too nervous. Anyone else have low HCG and everything turned out ok?
