Stopping of pills my effect kaya sa menstrual cycle?

Tanong lang po mga momshie last December i had my period and lasted on New Year's Eve, I am on pills recently pero nastress ako sa prep ng baby ko for upcoming bday party niya so I got lost count on my pills and nagdecide ako I'll start another pill after nang period ko. Nag do kami once a week and all are withdrawals which is very expert on his part. Pero up until now wala pa akong period. Pero walang sign na pregnant ako. Pero parang lagi akong nagkakamenstrual cramps. Is it possible that it is the effect of the sudden stopping of my birth control pills po? #1stimemom #advicepls
