I have experience with both of these things: They found a rather large SCH at the beginning of this pregnancy, and I’m on Lovenox.
First, be glad it’s a “small” SCH. U/s techs see a lot of these, so she knows what she’s talking about. The Lovenox may or may not make it more likely to bleed… All of this is a sort of wait-and-see, inexact science.
You MIGHT bleed. I bled a number of times before mine started to heal itself and shrink, and each time I was terrified that it was the end. (Quick note: I was pregnant with triplets originally and lost two of them, but not because of the SCH).
They monitor me almost weekly and it all looks better every time – right now, there is virtually no SCH left at all. I am 14 weeks pregnant.
I don’t know why you’re on Lovenox, (I’m on it for antiphospholipid antibody syndrome), but after the first major bleed, my RE ordered me off the aspirin on the side. It might be a good idea to ask your doctor if it’s time to stop taking yours too.
In the meantime, try not to get toooooo worried. Easier said than done, I know… I freaked myself out by looking everything up on the internet as well. Just play it a day at a time and take it a little slower than you normally would. Most of the time these things heal themselves.
