Hi Lyra!! Congratulations!!!
The contraction should be the stretching of the womb esp if you're first time pregnant =)
Like you, I am working and morning sickness, I would puke whatever i ate and I had this super bad headaches and fever (that went away finally after taking panadol prescribed by gynae) I even puked out my plain biscuit (no taste no nothing also puked) .. I was like you also, so sad and depressed, i cried everyday for that one week and even asked my husband if we could terminate the pregnancy.. Luckily for me, he supported me and coaxed me every night and super lucky, i only had MS for 1 week = )
Stay strong for your baby.. After 9 months, you'll see that everything is worth it..
