Hello. I'm Dr. Christensen.
First, congratulations on your pregnancy!
Without an examination it's difficult to say what the spot on your face might be. During pregnancy, normal hormonal
changes can cause several changes in your blood vessels, including dilation, congestion, enlargement and instability. This can lead to the development of a variety of skin lesions, many of which resolve following delivery.
(also known as spider angiomas) and cherry angiomas are fairly common during pregnancy, and they occur primarily on the face, arms, neck and upper chest. These lesions are most likely what you're dealing with. When traumatized by scratching or picking, small angiomas can bleed quite briskly. When bleeding persists, "spiders" and "cherries" can be treated with electrocautery or chemical cautery.
Pyogenic granulomas are less commonly seen during pregnancy. These lesions could start out as a small red dot, but they grow fairly rapidly into a fragile, bloody-looking nodule that is easily injured. Removal of pyogenic granulomas is a bit more difficult, and they sometimes recur. However, most pyogenic granulomas that form during pregnancy resolve postpartum.
I hope that answers your question. Good luck with your upcoming delivery!
