On so I had a d&c; on 6/22 with twins that stopped growing at 10.4w. I bled for two weeks until 7/4 and bd on 7/5 and on and off since then. I have spotted off and on last week so I thought it was my period trying to start because I had been getting all negative hpt telling me my levels were at 0. But it never came and I stopped spotting so I took another test on 7/23 and got a bfp luckily it was the day before my 4 week follow up so I got a negative urine test with her but a positive blood test of 9. I go back tomorrow to see if my levels are still going down or if I'm actually pregnant again I took a test that night and got another positive and even a darker positive today. I'm so confused how could it have happened so fast and if it's just left over hcg why would I get a weeks worth of negatives then all of a sudden start to get positives again!? I guess I'll know for sure tom. (Top white test is the one from a few weeks ago that's negative and bitten three are from the last three days)
