Short sharp pain

I have had a pain every naw and then today, rite at the bottom left of my stomach/groin area, it's a bit of a short sharp pain, never experienced it before, I am 8 days away from my next period being due and have no other symptoms apart from being quite tired (I work 10 hours a day minimum tho) also had a really sudden sick feeling this evening that was gone about 5 minutes after it started...any ideas? Thanks 😔
