It only speaks well of you that you don't want to harm your baby by using, but as Ms Diz said, wds are very taxing on your body from a lot of view points.
Listen to her and Yubacity, go to yours or other doctor and tell them the situation. If they have or have not prescribed you the drugs you are wding from, or what they may or may not think about it is not the question here, keeping you and your baby safe is.
Ask them and research about the safety of pregabalin during pregnancy. If it is safe, it will help you like no other thing, and if you have any doubt about how to use it, Yubacity will fix it up.
By the way, I am also catholic. I am pro life but also pro freedom. I find it great that you want to have your baby and I support you, but if YOU, and no other person, were to think that you should abort, I would be also there supporting you.
I dont think your friends have the right to tell you to abort if you don't want to, but neither has your Irish catholic family to disown you if such were your will. People always have their religion in mouth, but it is not the same religion that I was thaught as a kid, one wich says:
"Don't judge and you won't be judged, don't condemn and you wont be condemned. Forgive and you will be forgiven". (Luke, 36-38)
Good look and much love, amiga.
