When is it best to test?

Addie • Baby #1 and couldn't be happier!!!! 👶💖

Surely, by now, I would be having symptoms of AF. but I've had tender breasts for about 3 weeks and they've also grown... I'm having CM that is light, almost like it feels like I started my period but when I go to check it's just a kinda clear, light white CM.

Last night, I slept horrible and woke up in the middle of the night with terrible cramps, but no cramps like I've ever had before with AF..

Are any of these symptoms indications I could be pregnant? AF due 6/26 according to Glow.

Any advice is helpful and much appreciated ladies! Thanks☺
