Okay so I had my 6 week check up a month ago already. I got back on the depo shot that day too. Now I went back to work last weekend and this weekend. Well last weekend only worked Saturday and it was a easy 12 hour day this weekend I was put back to doing the regular job which I work in a warehouse and I was in the mods throwing thousands of cases and Saturday I went pee and when I wiped there was light blood so I got a tampon and couple hours later I got home and changed it and no blood on the tampon went to bed woke up went to work happened hours later again did the same thing no blood on tampon. Then today same thing and both nights went to bed and no mess. I was on the depo years ago but never had a period or did I bleed. So my question is did I wear my body out to soon from having a baby or is this just a light period and I’m to afraid to even ask the other question bc we have had unprotected sex but I’m on the shot and have had it all run out of me but I go to the doctors on Wednesday but I figured I ask here to the moms who are on the depo and if anyone works in a warehouse like I do
