i came off the depo 5 weeks ago, and i was wondering could i be pregnant because nearly 3 weeks ago i had unprotected sex multiple times, now im getting pregnancy symptoms like being really tired, have dark blue veins suddenly appear over my breasts, cramping, feel sick now and again and headaches:( could i be pregnant or is it me just hoping??

Well, the main thing that you need to stop and think about is, when was your last period, or when were you suppose to have your last period... The next thing that you need to do is go to a free clinic and get a free pregnancy test, all it takes is a little pee and you will know if you are at least 1 week pregnant.
