Hey, I'm just wondering if this is normal? At 7 weeks I was diagnosed with hyperemesis, and was on medication and had IV lines in every week up until 13-14 weeks. I was fine after that no nausea or vomiting I'm now 18 weeks and the past few days have just been getting sudden onsets of vomiting a few times a day and I'm just wondering if it's normal or I need to consult my doctor about it. Thanks in advance for any help!
