It is common to experience tightening in the abdomen during pregnancy, especially around 36 weeks when Braxton Hicks contractions become more noticeable. These are mild contractions that prepare your body for labor. They can feel like a squeezing sensation or menstrual cramps and may last for about 30 seconds to 2 minutes. It is normal to feel them several times a day, but every woman's experience is different.
Vomiting does not directly trigger Braxton Hicks contractions, but dehydration from excessive vomiting can contribute to their frequency. Make sure you stay hydrated by sipping water throughout the day and consider drinking electrolyte solutions if necessary.
If you are concerned about any changes or have severe pain, bleeding, or other unusual symptoms accompanying the tightening sensation, contact your healthcare provider immediately as it could indicate preterm labor or other complications.
Remember that every pregnancy is unique, so if you have any doubts or concerns, it's always best to consult with your healthcare provider who can assess your specific situation and provide appropriate guidance.
