Confirmed Pregnancy

Hi Mommies! Recently na confirm na namin ma I am on my 10 weeks and 5 days of pregnancy. Niresetahan ako ni OB ng Heragest (Progesterone) para daw yun iwas cramps, kasi mejo may na fefeel ako light cramps minsan. Iwas daw miscarriage yun. Mejo pricey po sya, may alam or may experience po ba kayo ano pedeng alternative? Thanks po.
