Hey guys I do not have a child and I took depo shot from March to June after that I decided to stop taking it, and now I experience spotting every time during sex and bleeding after that, is this caused by depo or I should see a gyner? Please help out

Both. Depo is one of the harsh long lasting contraceptives. It often takes a few months to a year to get over it. You should see your OB/GYN about this. She might be able to suggest something. Are you producing enough lube? Have you tried that? Feminine dryness does account for some bleeding. Regardless, see your gyner (I love that phrasing!).
