well we were ttc for 6 months (or maybe more, maybe even it was a full year, it was kind of on and off and i didn't count months) and i fell pregnant as soon as i started to workout regularly (after a month of fitness). just a suggestion!
What kind of work out plan did you do? I started about 8 weeks ago-doing all different kinds of cardio and weight lifting. But I have taken about two weeks off as I felt crap when I got last AF and then have had a hard time getting back.
OOH I love pilates but haven't done it in probably a year-will definitely have to go back!
