period questions!!

Aislinn
Hey all, 
We have just recently started ttc (9wks ago)  the first month I got my period regular and no real change. However this month I got it a day early (no biggy) however the flow was medium day one and then really light (spotting mostly). Also I get quite bad cramps usually and this month I got cramps the night before but the were full.. I almost felt like they were a warning of what was to come the following day however got none the following day. I have been off the pill a few months now so I know by body is not just regulating itself. I was hoping some of you may have some insight at all?!?! 
Thanks
