Nausea early on

I’m trying for my second child and two weeks ago I went off birth control. I immediately had a period, and glow says I ovulate around the 11th. However, I had egg white CM and a lot of it yesterday so my husband and I did the deed (that and the day before).

Anyway, I’ve been nauseous all day and super lethargic. I highly doubt it means anything, but I figured I’d ask. I’m not my normal self at all today but beyond that, I don’t feel sick.

Any thoughts?
