Trying to conceive

Kay

Hi, I️ know the feeling. I️ have been on Depo for over a year and was suppose to get my shot on the 29 of June and didn’t. I️ got first period on the 6th of August. Had unprotected sex every other day. I️ have been feeling tired queasy, sore breast and been having cravings. I️ had light cramping last night but no AF. No period since then...I️ tested the day I️ thought my period was suppose to be here an got a bfn. What should I️ do??
