not sure if this is af?

[ariesmandy]

hey everyone, i had a mc on july 9/10 after almost one year of ttc. i just started spotting on sept 7/10. It has been on and off for two days but just spotting barely anything there. I am not sure if this is my af or implantation bleeding. It is really confusing me. Oh if this is my af it would be the first one since my mc. Anyone on here had the same thing for their first af? I have some symptoms of being preggo again like sore bb's, extremely tired, and nauseated at times. Also when would i be able to do a hpt? Its so tough because my sister in law and i were only one week apart before the mc and now she is still preggo and im not. Im just so confused
