i am wondering if i could be pregnant. got last shot of depo in sept. of 08. No period except some, very little spotting about a month ago. been feeling major prego symptoms have taken a prego test a month ago and came up neg. also went to docter 1 1/2 weeks ago and was also not pregnant. was it maybe to early to tell. also every time i have intercourse i cramp up down there when we are done. that has been happening for two weeks. could i be prego or could it be something else. and if could be something else what so i have some sort of idea. scared and very confused.
