Help. Heartburn, discomfort and constipation

sagy

My ovulation is tomorrow, could I be already pregnant? Is it possible. I’m having discomfort lying on my stomach and heartburn and constipation for almost a week now. I feel different in a way, Im not sure honestly but I feel something is happening in my stomach, I had a little sharp pain, it wasn’t painful but I definitely felt it. And the heartburn keeps increasing slowly. Please anyone having this? Is it possible?
