*TriggerWarning* Help

Im in an abusive relationship and have been biding my time to gather the evidence needed to leave because I have 2 children with them. And I just found out that I'm pregnant with baby number 3 in the middle of a move that we are doing. How am i supposed to make the move and leave when Im pregnant and have 2 children? And currently dont have the substantial evidence to hold any ground??? Im truly trapped now... and im scared how mad they will be when they find out, yet at the same time maybe they wont because they've been forcing another attempt to a baby without me wanting to.. im not sure what to do because i have no one to go to i csnt ask for help. Ill lose, i cant do this by myself.
