First time trying Althea Pills

Hello! This month lang ako na-diagnose na may PCOS ako. Nagpunta ako ng OB today and sinuggest niya sa ‘kin mag-Althea. So I have to drink this for 21 days then rest for 7 days after. Ask ko lang kung hindi ba advisable na mag-raw sex during the first box? Since first time ko pa lang. Although takot pa rin naman ako i-try hahaha.

Hindi kasi na-explain masyado ng OB ko yung althea as contraceptives, pero as pills for period nasabi naman niya. Hindi rin ako nag-ttake ng pills before. We use condom + pull out method lang. Thank you!
