Advice

Tomorrow I am 15 weeks, I still have cramps (quick level 2/3 pain) and my stomach isn't so bloated.  I don't have too much of an appetite, but have cravings.  Is this normal? ...  My emotions are so up and down.  One minute I'll care and cry and be sad, not so much mad.  Then I'll be happy as can be.  I noticed that today I was supposed to see a friend, but their family was in town and they asked for a rain check. No big deal... But I cried and was hurt.  I'm not so much anymore.  Is this normal?
