My periods can be irregular but my last period was December 6th-9th and according to glow I was supposed to start on the 25th... Today is the 1st and Still no sign of period. On the 30th when i went to the bathroom i wiped and it was light pink blood only 1 time and hasnt happened since then. My boobs are sore and ive felt just slight cramps here and there. The nurses and my coworkers at my job swear up and down I am pregnant , But every test comes back negative 😢😢 Is my mind just playing tricks on me ?
