So I have very typical PMS symptoms that are the same every month. This month I didn't get them but I knew my cycle was coming because of my <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">period tracker</a> apps. Im usually Not more and 2 days off but tomorrow will make me 3 days. On the day my period was supposed to start, I started having really bad back pain and migraines also I'm super horny. Does that sound like I just ovulationed late? I was going to test if Mother Nature doesn't visit me in a full two weeks. What do you ladies think?
