Well ladies i miscarried at 9w5d sac empty measuring 7w4d ...had medical management and miscarried that evening. Had one week of period like bleeding only heavy the day i passed, for a few hours. Then the following week was 7 days of brown mucousy spotting. I have been doing preg tests and two days ago were so so so faint when they dried, barely visible but today darker than what it had been two days ago...😶 so confused!!! I have started to feel nauseous since yesterday as well and not sure what to think!
