Ive been having pregnancy like symptoms like stomach burning,nausea, recent mood swing. The stomach burning made me unable to attend classes for a while and it doesnt seem like it going away anytime soon. Ive had a weird stomach feeling 2 weeks before so i took a test and it came out negative. Last night i decided to take  another test again when i started feeling  my stomach burning for more than a day and it also came out negative. 

I have irregular periods so theres no exact date when to know if i missed it or not.
