Chemical or What?

So a friend of mine tested positive over the weekend. Started bleeding Sunday/Monday so she figured it was her 2nd chemical pregnancy. She got bloodwork Monday afternoon, & got results today (She’s still bleeding, too, like a normal period). Her HcG was normal levels at 27 so her doc wants more bloodwork tomorrow AM.

Her last chemical the lines on the tests disappeared immediately when she started bleeding. She tested tonight but her test is way darker than the previous ones she took. What in the HECK is happening?

Anyone bleed like a period with clots & such and still have a normal pregnancy?!! She’s so confused & just looking for answers.
