Frequent Vomiting And Stomach Cramps

Hi, I am now 9 weeks into pregnancy and I have been experiencing really really bad nausea and vomiting. I could be just walking normally with an uncomfortable feeling in my stomach, and will start vomiting every now and then. All around waist area will be aching, and I am unsure if sometimes it’s due to the clothes I’m wearing or it’s just normally bloated as I have read on some articles on the internet. Due to this, it’s hard for me to take in any food or drinks at all without actually puking it out again. Any suggestions or advice to improve on this? This is my first pregnancy..
