Newbie question sort of TMI..

Kristen • 👶🏻 💙
I'm new to TTC and I ovulated 1 week ago so my husband and I had sex days before my peak and after my peak. I did a CM check today (8 dpo) and CM is clear and not clumpy. I have some discomfort in abdomen sometimes during the day and I feel like my moods are off. Could there be a chance that I'm pregnant yet?? What's the soonest I can test??
