Questions!

I need some help the day my last period ended was August the first I still have yet to have another period and am over a week later than I was supposed to have my other period I mean I have literally taken so many tests I’m not seeing any lines I’m 6 months postpartum and I’m very confused is this normal not normal? Have you had this happen before? Give me advice my doctor is closed i tried calling. And I’m really not sure where to post this either so I apologize if it’s not in the right place
