Miscarriage Question! HELP

Kelly

Saturday I started spotting- went to dr on Monday for an ultrasound i thought I was 7 weeks exactly but just got off IUD in September got pregnant right away and miscarriage at 5 weeks so wasn’t 100% sure due to getting pregnant again the following month. They saw sac and measured me 5w2d. My blood work from my first appointment which was Friday was 3,090. Monday they took more blood work and said it only went up 170 hgc so they told me I was having a miscarriage again... I am still bleeding but as of Wednesday it’s filling 1/2 a pad every six hours so more than the first 3 days of spotting. I just got over a miscarriage from the month pervious and within 2 hours of bleeding I was filling a pad every 45-60 mins for two days. This time it’s different it’s not heavy at all I still feel pregnant and I’m just wondering has anyone experienced this ? I know my levels didn’t double but idk I still feel like something is not right?
