TW Miscarriages mentioned!

Back story I’ve had 3 confirmed miscarriages this year first one in February. I started bleeding on Friday (12/3) pretty heavy and it didn’t seem like a normal period so I took a test and it was positive. So I assume another miscarriage. I let me midwife know and she agrees that’s what it sounds like and I don’t go in. She also told me they just got my test results in and my folate was low which is consistent with early miscarriages. I never took tests to watch the line get lighter to make sure it was negative with any other miscarriages. Tonight I took a test and the line is actually darker. I bled heavy for about 2 days then I’ve had on and off spotting. Here’s the extra kicker I can’t just go in and be seen because to top it off I’m covid positive. So I guess I’m hoping someone can tell me if their line got darker before getting lighter or if they bled heavy and were still pregnant. Idk.
