Nausea sickness

Hi mummies! Anyone here still has nausea at 12wks +? Based from my prev pregnancies,it should have subsided by then but for my 3rd,it still feels the same. Doct wanted to prescribe anti nausea meds to me but I just want to monitor and let it go off by itself. Hopefully it does not go on throughout my pregnancies cos I want to cry! 😫
