Concerned About Cramps?

I'm around 5 weeks pregnant and having severe gas/bloating and constipation. It's creating occassional sharp pains in my lower abdomen. I had IBS before getting pregnant and my pain is normally on the right side. That's where my pain is mostly focused in this case as well. But I know one sided cramps can also mean ectopic pregnancy... At what point should i be concerned?

The pain isnt consistent and pain level is only uncomfortable like really weak cramps.

Sorry if I sound like a worry wart, this is my first pregnancy and every little thing has me anxious.
