Regretting depo so much

LaLa

I got the depo shot on a whim in July because we weren’t sure we wanted any more kids. I haven’t been on birth control in over 10 years. Once I met my now husband it was always pull and pray until we wanted kids. We have two girls and we are not certain we want another child.

Obviously I’m not going to get another shot but wondering if just one shot would take long to wear off?

I’ve been spotting brown since Aug 21 and got a period a week later which is just ending now (still spotting brown) so I have no idea but man I regret the shot so much! I feel like I have no control!!
