I had very bad cramps at the beginning, and was convinced it was either ectopic or another chemical. U/s showed a healthy baby though.
The cramps got a bit more mild as the weeks went on, and mid 2nd-tri they were mostly gone (lots of scary stretching pains though haha).
In the last week or two they've come back- unfortunately they're still scary (but thankfully mild). Doctor says it's my body preparing contractions, but as long as they don't get regular, they're normal...
hopefully you manage to escape them longer than I did, but the doctors keep telling me some cramping is normal- just part of growing! (or dehydration- so drink up!)
