Past abortion... feel like the worst person on the planet

My ex husband threatened me and made me get an abortion a number of years ago. I’m now happily married and have been trying for baby #1 for 4 months. I know that’s not long at all compared to some couples. But I’m trying very hard to convince myself that I haven’t “missed” my one and only shot at being a mother, wishing I would have stood up to him. Any words of encouragement would help right now....
