Pregnant while on estrogen?

Ly

Very confused, was taking estrogen then estrogen and progesterone last cycle after a Hysteroscopy. Told I couldn’t ovulate, so we didn’t use protection.

Have a sonohystagram booked for Tuesday, so I took a pregnancy test today before starting antibiotics, and we saw a very very faint line.

Have you gotten pregnant in this situation before?

Cant get ahold of my doctors office, but am prone to miscarriages and want this to be a healthy pregnancy!
