Late again!

Alexandra • Mummy of a 5 year old Princess called Alyssa
I came off the mirena coil in the beginning of Jan 2016. Had a withdrawal bleed 2 days later. Then a normal period at the end of Jan. No period in Feb, then a heavy bleed beginning of March. This made my cycle 35 days long!
Now, I'm in CD36 and absolutely no sign of my period. Breasts are sore as hell. Has anyone else had the same issues? Been on the mirena coil? Or is just late? Let me know xxx
