Hi! I’m sorry to bombard you, it’s ‘blue bean’ girl. I saw the advice from the other anon. I’m really grateful for the contribution from the community here. One thing I failed to mention in my original post (because it wasn’t relevant) is that I am a medical student. Only second year, but I do know that it is highly unlikely to be endometriosis. :) I will definitely have a check up if it persists! Just saying incase anyone out there has the same and is freaking out.
