hi! i am breastfeeding - a lot. my 13 month old does not love to eat solids and so i am taking up the slack. but i would like to get pregnant again sooner rather than later, and my period has not returned. any thoughts on natural supplements, etc. that might help this? i was using progesterone cream when i got pregnant, but i am not sure if i can use when breastfeeding? any thoughts greatly appreciated!!
