CM - how do I know what this means

I’ve been on BC for 10 years (pill 7, IUD 3) I just took my iud out in September and my husband and I have been TTC since then. My doctor said it could take anywhere from 6-8months for my body to be adjusted to not being on bc anymore. My period ended about a week ago and I have just noticed that about two days ago for the first time that I can remember I have CM that is egg white like and very stretchy. I didn’t notice this any of the other months that I’ve been off of my bc. Does this mean my body is regulating back to pre hormones?? Could I get pregnant? TIA for any insight!!
