I have been on the depo shot since march 2010 when my daughter was born and i have missed my august shot (2011) and i have been feeling like i am pregnant. the queezieness, dizziness, and tired all the time. i just found out the not only one of my boobs has the colostrum in it when only the right one had it. is it possible that i am pregnant? i am 42 yrs old and i need to know if there could be a way that i am expecting so that i can get the proper care for the baby.
