I am almost 3 weeks delay now and i tried using Pregnancy test and it's negative. It is the first time that i got delayed for a long time. I can feel some changes on my body like nausea, i get mad easily especially with my kid. I have a 6 yr old daughter and lately she became so active that makes me mad or upset. I get so emotional and sensitive even on little things. I am planning to visit my OBGYN on the end of this month. But i just wanna ask if any of moms here experienced having a delay period for a long time and tried pregnancy test but the result is negative? Thank you
