Poor you. I expect you are all over the place, if you have just found out. I had the same thing - it happened a long time ago now, but I remember how very sad and distressing it was. If you needed someone from a church to talk to/?check with, you could phone any local vicar of course.
Healthwise, and for the future, I would try to avoid infection, if I were you, so you might want to take the likelihood of that into account when choosing your options.
You know, don't you, that this was not your fault? Not lifting books or drinking coffee ... if that baby was going to stay, it would have stayed.
I am trying to be very careful not to say anything which may sound crass, or to upset you. An ERPC may be physically like an abortion, but it's not the same thing. You are not choosing to end something. For whatever reason, the baby is no longer viable, and it becomes a physical need to sort out, not a spiritual or ethical decision. It's a purely medical procedure now, so that your body can be healed, and to enable you, if you wish, to try again in the future.
I wish you well.
