My period was due December 31st,2018, I still haven’t seen my period. About two weeks prior to this I was having on and off mild cramps, a headache along with nauseous once or twice a day. About a week ago my boobs begin to get really tinder and swollen. On wed Jan 2,2019 I have a very small amount of brown discharge. When I wiped and haven’t had any more since. I took about 2-3 pregnancy’s test this week so far and all negative. Today ( Jan 4) being 5 days since my expected period I checked my cervix and it feels high and like puckered swollen lips. Still no signs of period. And still have tinder boobs and light cramps once or twice a day.
