What is happening. Help?!

Brittni

So going on 5 weeks post d&c.; On 29th level was 76. On 31st it was 43. Went back on 9/8 I was at 15. I was thinking I would of been at 0 2-3 days after the 31st. So I wasn't sure if the 15 was from me being very early pregnant based off the chart cause that would be right I'd only be about a week. But today I'm having some cramping and when I pee I'm bleeding but I don't need a pad or tampon. But I have a faint positive pregnancy test. What's going

on ladies ?
