Pregnancy with uncomfortable pain/cramps at 16-17weeks

Patient: Hello Doctor, I am 16-17weeks pregnant, 4days ago I experienced a sharp pain in the middle of my stomach and after that I’ve been having an uncomfortable pain on my left side. I am not bleeding, I had a chat with my gynaecologists and she said its fine if I’m not bleeding. Could I please get your opinion, is this something to worry about? its my first pregnancy.

Symptoms: Pregnant with pain on left side
