I'm 4 weeks and I've also been getting strong cramps since week 3, but I saw a doctor yesterday and he said it's completely normal. We will continue to feel the cramping all throughout the pregnancy. I read online that doing stretches helps!
Thanks for all the responses, I do feel at ease. And I will definitely try the water when I wake up.
Try keeping water next to your bed before you get up drink it it should help:)
Cramps can continue through out as your uterus grows. It's perfectly normal as long as there is no bleeding or they are really bad. Call midwife and ask for a scan if worried.
Good luck xx
