4 weeks late

Amy

I am now 4 weeks late on my period.

The last time i had my period was the week of April 24- 30.

Well before that period i was on BC pills.

Me and my fiance decided we wanted to ttc.

Well every since i didnt go back on the pills my af never started.

I know im not pergo because i had a blood test done last week.

Im so confused on whats going on with my cycle.

Could someone help me or tell me what i should do?
