Pregnancy literally changes everything from head to toe, even our nose blood vessels! It is fairly common, but don't just sit on it. Do mention it to your doctor to ensure everything is fine.
It can sometimes happen due to increased blood flow, but please don't take it lightly. Let your gynecologist know immediately so they can check your blood pressure and make sure everything is safe.
Oh, experiencing a nosebleed when you are already dealing with morning sickness must be so scary. Please lie down, keep your head elevated, and call your doctor's clinic to let them know. They will guide you on what to do.
My hospital nurse told me that pregnancy hormones can expand blood vessels, causing occasional nosebleeds. However, you must inform your doctor or visit the hospital to rule out any high blood pressure issues.
Actually, the blood flow increases a lot during pregnancy, which can cause rare nosebleeds yaar. But honestly, please check with your gynac once just to be on the safer side.
