Peeing / leaking during early pregnancy?

Kayla • Due 10-11-16 with Tobias Ray 💙💙
So I'm only 5 weeks according to my last menstrual period. But yesterday at work I stood up from my chair and felt something leak down there. Went to the bathroom, no blood but couldn't tell if it was pee or what. It was enough to go through my underwear and leave a wet spot on my pants. Felt just like a small gush. Is this normal this early on? Any help or opinions would be much appreciated 💕💕 I could be further along too I haven't been to a doctor yet. I have an appointment on the 26th thank you!
