My husband and I were trying for a year to conceive DD2 - he worked a 3-1, and a 2-2 roster over that time. It was a completely frustrating PITA. But we got there eventually.
Thanks so much for the replies! Before my daughter and before fifo it took two years cos my cycles vary from 30-60 days so when we start trying and i take out the mirena I have no idea what yo expect...
