Hi All... Ok I have been doing a lot of research looking for the right answer and most are split down the middle. I am 25 never been pregnant. I was on the Depo for 3 months then did not go back for the next round which should have been done on Sept. 19th. Now just last Monday 10/19 I have been doing so unprotected for a few days w/my bf. I have never had a regular period. My question...how soon can you show symptoms? And can you become pregnant only after being off Depo for a month? Because, I started to be very sensitive in my breast area. Began vomiting in mornings not capable of holding anything down until evening. Still constipated and diahrrea ocassionally. Lower back hurts. Did have some strange spotting for only 2 days (which is never the case for my periods). Exhausted constatnly now and headaches. I know some can be symptoms but not ness.all. Please let me know your opinions or experinces in relation. Thank you!
