I need advice asap!!

So basically my mom told me she found out she was 8 weeks pregnant after going to the hospital for a blood clot related to having factor 5. (rare blood clotting disorder) Because she is 40 and has factor 5 continuing the pregnancy would mean she would have to get a blood thinner injected in to her belly every 2 days and she would be on hospital bed rest for the last 4 months of pregnancy. My mom is making the decision to get an abortion because of this as she doesn’t leave all of my siblings and I motherless.

I’m 18 years old and 5 weeks pregnant, I have yet to tell my mom. I wanted to wait for the right time to tell her and now I feel so shitty because she has to get an abortion. Our due dates would have been around the same time.

Can someone please give me non-judgemental advice? I’m not posting for attention either hence why I made the post anon.

Update: factor 5 causes blood clotting during pregnancy making it high risk and with my mom being 40 it would be an even higher risk
