Nausea usually starts around the 6th week for most, but every woman is different. However, if you are vomiting too much and feel dizzy, please check with your gynac immediately. Don't take any medicines without their advice.
It actually starts around the 1st or 2nd month, yaar. For me, the evening nausea was worse than morning sickness! Try having some cold jaljeera or nimbu paani, it really helps soothe the tummy.
Listen, there's no fixed rule, but most ladies get it between 6 to 12 weeks. If you are feeling nauseous, just rest and don't force yourself to eat heavy meals. Keep sipping water and eat simple food.
With my PCOS history, I was constantly worried about my hormone levels. But my nausea started right around week 6 and lasted till week 13. Just stay positive, eat small portions, and take it one day at a time.
During my pregnancy, the nausea was quite bad from the 6th week onwards. Now that I am breastfeeding, I realize how fast that difficult phase passed. Try having dry crackers or biscuits right before you get out of bed, it really helps.
My saas told me that nausea means the baby is growing well, which made me feel better. It started around my 2nd month. She used to give me dry ginger pieces to chew on, and it worked like a charm!
