Ovulation

Hi ask ko lang po if nakipag do ako ng 5days after ovulation ko safe po ba yun? 29 days cycle and regular ako. withdrawal lang kami . possible bang mabuntis? nakakaranas po ko ng mild headache may ilang araw na. Cramps at discharge na watery at minsan creamy white na parang lotion. sign po ba ng ovulatioj to or early pregnancy
