So I need to know if

Had my daughter three months ago. EBF her. I had my period on the 12-25 (13 days long) in sept on the mini pill. This month ( he ejactulates In me every time since day six of pills last month.) I took a test on the 14th of October just in case.. Still no period but I am cramping and had some brown spotting for like two days. Should I retest?! Still no period as of November 3.
