Hi, I m 24 years old, located in Texas, and I work as a vet tech.. I have a few questions to ask. My first is about infertility.. I ve been trying to have a baby and I keep up with my cycle and all but every month I keep getting my period. But my periods have been odd lately. My periods will always start out very very light and the next day will be light to medium then the third day I just kind of spot throughout the day but then I keep spotting for about 5 days after my period ends. My last recent period the very first day the blood was dark brown almost black then the next day it turned into red brown but with my normal flow then the third day I spotted red lightly throughout the day. Then spotted for about 4 or 5 days after. Is something wrong or am I just not fertile.. An also I don t have a lot a money to be spending for expensive doctors
