I had a MMC in 3/12 after almost a year of infertility. Ever since my D&C I've been getting a wipe of bright red blood every 4-5 days along with brown spotting. I tested negative on 4/1 but positive on Thursday. I had my hcg tested Friday and it was 24. I go in tomorrow for a repeat hcg but I'm pretty sure I'm having a chemical pregnancy. My line isn't getting darker and I'm still having a random wipe of red blood. It's not like a period though. I'm just not sure what happens after back to back losses. Is there a certain type of blood work I should be asking for?
