Hi.I am 17 weeks pregnant and I have endometrioma on hoth ovaries.My physucian in Egypt suggested to take cyclogist 400 mg daily at night to decrease the incidence of preterm labour as endometrioma causes increase risk of preterm labour by 33% than normal prefnancy. I am in the US and they don t recommened taking it. Also I ve read cyclogest may cause defects in the genital and hormonal systems of the baby both sexes. I took 400 mg for 2 nights,I feel I am not comfortable with it,please tell me what is the best to do and how should I stop taking it, can I stop it suddenly or it s of risk as the body may understands this as labour or should I devide the dose then quit please tell me how to stop it and if it safe on 1st place or not. Thanks a lot
