Hello, I've been experiencing what I think are pregnancy symptoms, I was supposed to start my period on the 6th of this month but it hasn't arrived yet (11 days late so far) it is cycle day 43 and ive been experiencing pulling like pains ( not painful just uncomfortable ) in my lower abdomen, nausea mostly in the morning's, loss of appetite, runny nose on and off, sore throat that comes and goes, tired more than i usually am , heart burn and my nipples felt tingly at some point. I have been checking my cervical positions and after i ovulated around 1-2 weeks ago it dropped and became firm. The following day it started rising and becoming softer and closed. Now its is so far up i can hardly reach it with my longest finger and it is soft and closed. I decided to do a pregnancy test and it showed negative ( clear blue digital weeks estimator ) I am so confused could i still be pregnant ??
