Well, good. This sounds pretty normal.
You really think your boyfriend is going to be angry? Are you afraid to tell him because he'll leave you or suggest you have an abortion or something like that? Have you been able to tell anyone sweetie?
Yes!! Absolutely. Lots of women get cramps that feel like mild period cramps when pregnant and all is fine typically. If they get worse or you begin to bleed, then call your doctor. But I had what felt like a period coming on in both pregnancies in terms of cramping and in one I had early bleeding. Both pregnancies were fine. :>) how are other things going? Have you told your boyfriend yet?
