I got lots of period type cramping for the first 8-10 weeks plus sharper stitch like pains. There is alot of stretching and growing going on - lots of people get them and they are perfectly normal - if stressful at the time!

I should add tho the pains/cramps were not as bad as my usual period pains - a lot more dull and achey. If you are in actual pain or have associated bleeding you should see your doc. I took panadol a few times and used a warm (not hot) heat pack to ease the ache - especially to sleep at night.
