I was on lupron for six mths and right after I was on depot for three mths I decided to stop due to the side affects, my last depot shout was in August I was suppose to get the next shot Novemeber 23. I did not have a cycle the six mths on Lupron how ever on depot from October until now I have been bleeding , heavy at first now extremly light. Today my breast , nipple area are tender and I still have not had a full regualr cycle since before taking Lupron. On Christmas I felt cramping like I use to as if my cyle was getting ready to come on. I don t know what to do, could I be pregnant or having pre-mentral symptoms, it s been 4 weeks since last sexual incounter.
