AF 2 weeks late, not pregnant! HELP

[tannedangel]

My cycles are usually 28 days to the dot. Before the pill, during the pill and after the pill, and after birth.
Ive been off the pill for 3-4 months now, and usually after being off the pill my cycles dont change at all. I was on the pill for 3 years before I went off it and got pregnant 2 months later with my DD. My AF was back to normal after I stopped BFing my DD, and I went on the pill to clear up my skin.
I then went off the pill 9 months later initially because Id thought I may be pregnant, but I wasnt and decided not to continue with the pill. Ive had my withdrawal bleed and 20 days later I got my first AF.
Now Im on CD41 of my cycle, and no sign of AF. Im 13 days late. Although I will add that I did have what seemed to be spotting at CD20 for 4 days. I would bleed a very, very minimal amount, and then it would stop for about 6-10 hours, then another small bleed and so the cycle went for 4 days. My AF is always heavy and very crampy. This was just spotting for a few days with no pain.

I dont know whats going on. The DR said that if Im not pregnant, that Im not ovulating, and to give it a couple of months and if my body doesnt go back to normal to go back and have blood tests (every week) to check my hormone levels and determine whats going on from there.

Im very scared because Ive been very in tune with my cycles since I started, they have always been dead on 28 days, 30 days maximum, and this is the first time that its been this late without being pregnant. I can usually feel myself ovulate (little twittering feeling in my ovary area) and Im pretty sure Ive felt it this cycle.

I feel like my body has let me down or something, I just want it to go back to normal already!

Anyone?

I was always very regular but i did have a cycle where a/f was 5 weeks late and i wasnt pregnant. I didnt go to the dr so not sure what caused it. Maybe wait another week and get a second opinion.
