Okay so I have never been regular so I don't really know what my periods are like I have been on BC since I started my period and I got off of it in July and got pregnant in  August and MC in September. AF never came until December 31-5 so I don't even know if I'm 28 D.C. Or 34 DC if I'm 28 then I should have started Friday 1/27 but I have absolutely no signs. How long should I wait till I test?
