I am 21 weeks and still get lightheaded especially while working out. I have to up my water intake and listen to my body to slow things down.
I agree. Sounds like low blood pressure, increase water consumption and salt intake. Best of luck, and congratulations on your pregnancy!
I had low blood pressure during my last pregnancy which I didn't experience prior to falling pregnant. It made me feel faint & a few times I passed out. Dr told me to increase my salt intact & it did the trick. Ask Dr to check your BP.
I always felt very light headed in the first trimester of all my children. Your blood pressure might be low. Drink plenty. Get it checked out for your own peace of mind.
