Is this normal? Long term BFing?

[Felicia_D]

So I've BF'd both my kiddos (DD self weaned at 4 months tho) and still BFing Ds going on a year Friday. After having DD my periods came back after the 6 weeks PP and stayed regular until I fell preggo with DS (could expect AF down to the hour-even while BFing DD and on the Pill).
I forgot to mention that DS is currently only nursing 1-2 throughout the day and maybe 1 time at night (with the exception of this last horrible teething week that just seems to continue ).
AF returned in August at the 6 wks PP mark with DS as well. But this is how they've gone since being PP:

Aug 10: Last 3-4 days (4th day spotting) Cycle lasts: 26 days
Sept 5: Lasts 8 days (last 2 days spotting-again) Cycle lasts: 39 days
Oct 14: Lasts 5 days (again spotting on day 2 and 5)Cycle lasts:101 days
Jan 23: Lasts 7 days (spotting on day 7) Cycle lasts: 39 days
March 3: A whole 2 days of spotting and then nothing. Cycle lasts: 47 days
April 19: Lasts 5 days with only spotting on the first day-so much like my "old" AFs=so much hope of it being regular again
And then NOTHING since April.
So far I'm on day 83 with ALL of the PMS symptoms and the cramping, but no AF. I've taken about 4 tests and they've all been diff brands, diff times, and have all came back .
Don't get me wrong, I'm not exactly wanting a any time soon, but I'm just starting to wonder wtf is going on and if this is "normal" when it comes to BFing this long?

Yes it can be normal, it could also be due to low progesterone which is linked to b6 deficiency, however unless you have any of the negative symptoms mentioned in this article

Or are looking to TTC really soon it's not necessarily something that needs anything done about it xx
