Greasy Hair

Devon • Our 🌈 due May 2018
My husband and I are TTC for our first child and I am supposed to get AF Sunday, but glow is telling me to take a pregnancy test. I haven't felt any different with the exception of my hair, it has all of a sudden gotten really greasy, like can't go more than 24 hours without washing! I have super normal hair so this is really new. Has anyone else experience this?
