Hi! It has been a few weeks since I started feeling nausea and at times, I need to vomit things out to relief it. During those weeks, I have also experienced a pinching pain on my lower left abdomen and feeling of being full on my tummy. I also had experienced right chest pain once and a twisting tummy feeling (that disabled me from walking) once. Few days ago, have started noticing constipation. Boyfriend kept panicking over pregnancy but I just had my regular heavy period last week. What is it
