Birth control tips

Hi! I'm a first time mom at kapapanganak ko lang last Oct. 20. Yung asawa ko kasi nangangalabit na HAHAHAHA pero natatakot ako kasi baka mabuntis na naman ako agad, eh ang balak namin is after 5-6 years pa susundan si LO. Any tips or anything na effective gamitin, inumin, or whatever para hindi agad mabuntis? Thank you in advance! #1stimemom #advicepls
