Really emotional without my boyfreind here?

im feeling kind of sad my boyfriend went away for a week to wyoming with his dad and stepmom to go water rafting camping and hiking and he promised me that he would call the first night and its the end of the second night and he still hasnt called and im super emotional now more than ever cuz of the baby cookin inside me makin me even wackier than i already am and something made me laugh histarically earlier today and i thought of him randomly and i started crying hysterically at the same time! it was soo crazy and it was soo hard to stop! like im a pretty crazy laugher ever since i was a baby my mom said and one time my teacher in the 6th grade called the office because she thought that i was having a seizure lol!! so even with my insane laughing past i thought that the laughing-crying thing was pretty weird!! so is this normal? has anyone else experience anything similar to this? and is the father of my baby not being around have anything to do with it? cuz ever since he left on that plane ive been really snappy and rude crying-y and crazy lol
