miscarriage pill

I'm taking cytotec to help my body pass the baby I lost at 9 weeks. I'm just wondering if anyone has any experience with this and was able to conceive again. I'm starting to question my decision. I'm worried the pill with mess up my fertility and honestly I don't even think it's working. any advice would be great. I would also like to add the day before yesterday I inserted 4 and the next day another 4 and nothing happened yet. does it usually take this long?
