Early pregnancy... twins?

Jamie

I am almost 6 weeks pregnant with our fourth baby. So keep in mind I’m familiar with most pregnancy symptoms. For the last 3 days I have had the worst uterus stretching pains. I know my uterus is constantly growing but with my other pregnancies the cramping didn’t start until around 10-12 weeks. And being kid 4 I wouldn’t expect it to hurt this bad since my body has done this several times before. Anyone else experience such terrible cramping at 6 weeks? If so did it result in twins or anything I should worry about?

Thanks!
