Maybe this is dumb but idk who else to ask. I've been sick for two weeks, I'm 25 weeks pregnant and already have had a ton of complications that could cause possible issues with my placenta. I thought I had a sinus infection but even after taking 10 days of antibiotics, I've had horrible headaches. Similar to when I had COVID last year. I took this test and now I think I might've had COVID the whole time and I'm at the very end of it. Doesn't anyone else see that faint line??
