So i went to sleep last night with a headache im 6 weeks pregnant. Ive had really sore nipples since my pregnancy started. So i get up about twice at night to use the restroom. And this night was different i had the worst headache even after i feel asleep. I then got really dizzy. Even with my eyes closed i could feel the room spinning. Now this morning my dizziness and headache went away but so did my sore nipples. Show i be worried or is it just me?? Any advice??
