I trust him, I am just insecure

Some things have happened in the past, that are better left there, that have made me insecure about my relationship. Maybe it's just me, or maybe it's coming from the anniversary of the day my father made me get an abortion that's coming up soon. I have not been on birth control for a few months now to try and clear up the cystic follicles my iud helped produce. Secretly hoping that I will get pregnant soon. My periods have been increasingly late and shorter every month, so I suppose these hormones are driving me nuts. I'm not exactly sure why I am posting this, maybe for a little reassurance? I don't talk to many people and the ones that I do, don't really make me feel any better. Idk, I'm just all over the place and idk why I feel this way.
