Welcome to OhBaby!
And yes it takes awhile to get to know your body again after having a break.
Not sure what the standard is for Mirenjavascript:AddSmileyIcon('

')a's however my AF didn't arrive for a month and it took a couple of months to settle down.
In the meantime I would suggest you get a thermometer and start temping as it will help you understand your cycle. A good place to start (as they give information and guidance) is
Fertility Friend - it's free and it's easy to use.
if you do decide to temp and chart then feel free to come over to the charts thread and get the girls there to have a look at your chart
Good luck and i hope your TTC journey is short.
