HELLPPPPPP

So last month I had to have a D&C due to a MMC at ten weeks. Doctor said that with the procedure my period should start a month from surgery. Still no af. I’ve been taking pregnancy tests for two weeks to track my hcg and to see if it was dropping and It was. Then I took a frer on Tuesday and it was significantly darker. So I scheduled bloodwork for that day to see if I had fallen pregnant again. The results came back negative. I’m so so confused. I took another frer this morning and it’s still positive. Going in for more bloodwork on Monday to double check. Any thoughts or advice? I feel like I’m going crazy. 🥴🥴
