I have been really nauseous and at the verge of vomiting for more than a week, I am exhausted and have recently been feeling pain in my lower abdomen. I was supposed to start my period around 19th but started 11th for 3 days then stopped and then a little blood came 2 days later. I was on the pill but stopped taking it and had a normal period 21st of April. Then yesterday I had a little rubbery discharge with a little bit of pink in it. I ve taken a hpt and they ve all been negative. What could this be?
