Not pro life but need a point of view from someone that is

I have 2 adopted children I’m a foster parent I’m married and my husband and I tried for years for our own, so don’t come at me with any baby k!ller stuff. I just had a kidney transplant in may, my husband and I made an agreement to wait until I had an IUD placed before we had sex… 6 weeks passed, our anniversary came up one thing led to another had sex using sperm killer. Found out 4 days ago I am now pregnant. I am on a medication that I can not get off of called cellcept, it commonly causes serious birth defects, pretty much got a warning from every doctor that there would be serious complications with the fetus if it grew to term. No one really mentioned the new kidney but I can’t imagine that would go well either. First thing we did was contacted planned parenthood (after my ob/gyn) we didn’t make any appointments yet just wanted an opinion, they said you can take a pill 70 days passed your missed period to end the pregnancy. I’m pro choice but now that it affects our family I’m not 100% sure what to do. I don’t know if we will do it then regret it. If we do it and later not have another. But I also do not want to chance having a baby with serious birth defects some of those include organ damages, ruined kidneys, under developed heart… our other option was wait until 14 weeks and have a scan to check the fetus for any abnormalities that wouldn’t be compatible with life. But part of that seems pretty cruel.
