<s>[INST] Dear Doctor, TTC for 2 years with pcos , this cycle my dr prescribed HMG shots from day4 to day9, then trigger ChatDoctor shot on day 12, i ovulated day15, then he put me on cycloprogenova 2 white pills daily and told me to take it for 2 weeks bec my endo was 9mm. am on day 18 now, but am worried bec cycloprogenova is category x, and when i stop it would my hormones become low and if there s pregnancy i would have miscarriage? Thank you [/INST] Hi, As your endometrium should be enhanced for proper implantation should you conceive in this cycle, you would need the medication. Yet, estrogens are contraindicated when pregnancy is contemplated. Effect of hormones on the embryo has been seen after 45 days, so your doctor may have prescribed this now. Once implantation has occurred, you may not need the medication and supportive treatment is ensued, to prevent a miscarriage.  Please discuss with your doctor if you do not wish to continue the Chat Doctor.  Take care. </s>
