greasy hair as SUPER early pregnancy sign?

My husband (Brandon) and I have been officially TTC for 3 cycles now and I notice today that my hair is unusually greasy. My skin and hair are typically sooo dry and I have a minor case of exzema on my skin so I am able to wait about 4-6 days in between each wash which, if you have long hair like I do, is a tremendous blessing and time saver!! I recently had a 5 day ovulation period and am now waiting for my period to come and I noticed today that my hair is ridiculously greasy after 2 days of not washing it, which is very uncommon for me! Usually I don't see any grease on my hair, even by day 4! Has anyone had this really early symptom? At most I would be 2 weeks pregnant and the very least I would be a week depending on if we had conceived at the start or end of my ovulation period. I believe it is too early to take a PT. I would appreciate any feedback! I am also taking prenatal vitamins and a fertility drink. Maybe it is these fertility boosters? Idk! Just want some feedback! Thanks! 😀
