Cycle day 43...help me!

Andreia
My AF turned up today day 43 of cycle, have horrible cramps and AF is so dark, almost black and very clotty (sorry tmi). I have never had a cycle this long and now I think there is something really worrying with me?! I'm 32 and TTC second baby, only been trying for about 2 months! Should I be worried? Normal cycle is average 33-34 days 😞😞
