My goodness your DS is so darn cute!!! And WTG for exclusivly pumping! I pump 2x a day and really don't like it. But we do what we have to for our kiddo's.
Once you stop pumping your AF should return fairly soon. It takes a bit for your hormones to level out...I *think* it is like 4-6w but don't quote me on that.
For me I EFB both my children and AF returned at about 5-6 months for me both times. But everyone is different.
I am sorry you had such a hard time TTC your DS and I noticed that you are an angel mommy too...so am I. But having a baby really changes your body! There is a girl in my
PR who tried for 5y to get pg with her LO (born Aug 08) and she is now expecting a little suprise!!! I hope you have that type of wonderful luck too!
*Just curious but why are you going to stop pumping?
