Burning pain in lower stomach

[Charm_er]

Looking for some advice, I am getting awful burning pain very low down in my stomach. It comes and goes. Currently sat at work with a hot water bottle on my thighs (don't want to put it on my stomach) and it is helping a tiny bit but I can't stand. Feels a bit like an upset stomach following eating a very spicy curry. Now should I be worried? Do I call the doctors? I feel sick and a bit light headed too. I'm currently 8 weeks. Xx
