Okay, so I'm planning to conceive again soon, probably after my youngest turns one. Is there anything I can take to boost my chances? I've taken birth control pills, only the "breastfeeding safe ones" and I wonder if the pills put me out of whack or something. In the process I want to tone my body but like I don't really have the positive vibe to do it either. I feel like I should try toning first then. What do you think ladies?
