For the past 2 months, my period (which is normally 28 days) has started after only 24 days. November it was supposed to start on th 12th but started on the 8th. I don't remember the date, but my husband were active while I was ovulating. We weren't trying, just having fun. December I was supposed to start my period on the 6th but I started on the 2nd. As of today, the 29th, my period has not started. I'm wondering whether I am pregnant or whether I am going back to every 28 days. I have had puffy nipples and constant urination, so I am just curious as can be about when I should tesst.
