My hcg last Thursday was 14 that we have been trending down from my ectopic pregnancy, so it should be even lower by now. This morning, 5 days later I have a very faint line on my test strip. I didn’t think they could pick up lower than 25 hcg level. Is it possible it’s from the old pregnancy and not new? Anyone have a test read a super low hcg level?

Edit: also I should add that I had a positive ovulation test 12 days ago though I doubted I actually ovulated since I had 2 days of heavy bleeding during that time.
