So my friend took a test and it looks like a faint positive but last Thursday they said her tests was negative. Any opinions?

Add: she had an iud but it fell out and due to seizure medication she can’t take certain birth control pills so she’s been unprotected for a while and hasn’t had a period since November. She has 2 other kids and didn’t get a positive urine test till halfway through both pregnancies. She’s to the point of not knowing what to do since her obgyn says she’s not pregnant. She has an ultrasound Thursday

Update:

Hopefully last update: she went to the dr last week and nothing was found on ultrasound but blood work says she around 3 weeks. She had a seizure the other day and when she got to the hospital she found out she has Covid
