What do you think am I protected?

Just got the depo shot last Friday. Got my nexplanon (from excessive bleeding) out on June 8th still haven't gotten a period don't know when I would get one bc it can take awhile to get one after the implant.I Had sex 3 days before I got the shot idk if I could conceive from that. Should I wait a week or you think I am good. My OB told me since I have to go get the vile with the bc from the pharmacy and they'd be closed by then. I could do the shot myself so I did that. oh yeah please don't tell me how bad depo is bc I already read horror stories on it and the first 2 days on it it just made my anxiety horrible and I threw up tremendously the first 2 days I had it. For some reason any kind of medicine I get I have to read what people experience on it and it makes me freak myself out by doing that to where my anxiety will create the synptoms I read about that I wouldn't have got if I didn't so please spare me the anxiety attack.
