I had my first dose of the depo shot the last week of August and had unprotected sex like maybe 6 or 8 days after I'm not sure. I know that we had sex September 5 and like the middle of September I only had a brown discharge but would only show when I would wipe and lasted for about a day or two and been feeling nauseous, gassy, hungry, sleepy, my dreams have been very intense and vivid to the point were i woke up crying. I don't have to pee as much but it's had for me to hold it in now also it comes out to like a very faint yellow. Constant headaches and sometimes get lightheaded also my hair hasn't been falling out as much and that's a big change for me. I know that the depo shot mimicks pregnancy symptoms but this is different. Please help.
