Worried May Be Pregnant

Patient: I’m was on the depo shot for 6 months . I have no longer been on it for a month now. I have not got a.regular period I just spot everyday since being off. I had unprotected sex 12 days ago and the last two days I been getting dizzy and wanting to eat and then cant. Been really drained and lazy also. Anyway I can be pregnant. I know after the depo it can become very hard to have a.child until body becomes normal.
