I had a miscarriage at 12 weeks on October 22nd.. I started bleeding on the 20th and miscarried 2 days later. 2 weeks after the mc my dr told me my levels were back at zero, and on the 7th and 8th of novemeber I had ewcm that had old brown blood in it. I took a test yesterday and it had a faint positive and then the one today was negative. The blood was probably just left over, correct? I'm going to test again in the morning. First picture is from yesterday and second is from this morning.
