Early signs?!??

I am currently 5dpo, I ovulated on CD18. Today I have been feeling some twinges in my lower back and also still have quite a bit of CM. I am someone that is usually very dry- just started <a href="https://play.google.com/store/apps/details?id=com.glow.android">tracking ovulation</a> this month and it’s been the first month since trying that I have had lots of cm on my ovulation day. We have been TTC for 6 months. Could these be early signs? Going to test later on in the week but couldn’t wait that long to share🤣😫
