Planning on abortion next week :(

Next week on Tuesday June 13th I plan to leave work early to get an abortion. I will be 9 weeks and will be getting the pill. I have two children and can’t have another right now. Can anyone please tell me your experiences with the pill? I am terrified and scared. I have had losses at 18 weeks and 9 weeks due to chromosomes issues. Will this be like that. I’ve read nothing but horror stories about taking the pill. Thank you!
