Hi ladies! I'm 7dpo and Af not due until 9/10 
Can this be implantation bleeding??! I never spot this early in my cycle. Always a day before af arrives. I've been having brown discharge since yesterday...what do you think??? Please someone answer. I've been sending questions and no one has responded this past week. Thank you in advance!
