I had these through weeks 4 and 5. I went to the doc in week 5 and she told me that most pregnant women she sees feels "period like" with cramps, no motivation, nausea and being tired all the time. She did tell me that if I would start drinking more water (like 6 to 8 glasses a day) that the cramps would get so much better than they are. I started making a point to drink water all the time, and SHE WAS RIGHT! My cramps went away!! I still have the shooting cramps sometimes (which I guess is the uterus stretching), but that is it, so try drinking a lot of water and see if they lighten up! I'm still sicker than a dog with nausea, but no more "period like" cramps.
