I have been lactating for the past five months. It usually start about a week and a half or so before my period and has completly stopped by the end of a short (like two to three days) cycle. During those two weeks before though, my breast swell nearly an entire cup size and fell like they are hot with fever. The only way that I am comfortable is strapped up in a sports bra. I am 26 years old and at this point in my life I feel like my biological clock is ticking and I wonder if this is what is causing this. Could it be my desire to become pregnant that is making this happen?
