Birth control shot vs Spermicide

I have been on depo for 4 months almost. It has been a ROUGH time. From day one it’s been non stop nausea, dizziness and fatigue. I have almost no appetite ever so I keep dropping weight like crazy. Another symptom I have had since the start has been continuous tingling in my arms and legs, almost like they are about to fall asleep but don’t. My doctor said it could take some getting used to but this is almost unmanageable. When does it get to the point of feeling normal again? Not sure I can handle another couple months of this and I heard stopping the shot comes with its own set of issues because of your body trying to readjust again.

Getting off birth control and having cramps idk why I only been off for like a month or so

I have been on this form of birth control for 3 months now. I got my first dose on the last day of my cycle. This is my first time ever on birth control. After the first dose my cycle went away. I got my second dose 2 weeks later than what I was supposed to, because my gynecologist rescheduled my appointment (because they’d be closed that day). I started bleeding a medium-light flow 7 days after i was Supposed to get my second dose. I have been bleeding for 28 days straight now. The flow is the lightest it has been so far today, but it’s annoying to deal with. I get my third dose of depo in 2 months, and I’m honestly thinking of quitting it.
