Diarrhoea at 5 weeks!

Beth

I’m 5w2d with my first pregnancy. I have PCOS and we got pregnant on our first time trying, so I’m on edge about everything at the moment as it seemed too easy. I’ve been feeling a little bit sick, but nothing too horrendous yet, but I have been having diarrhoea for the past 3 days, which is causing stomach cramps and gas. Is this something to be worried about?
