So I’m taking another test tomorrow morning, but in the mean time my boobs are way more sensitive ( specially in the cold) and I can feel what feels like a knot in the same spot on both boobs. My period is a week late. Sore boobs are common for me during my period, but I’m on cycle day 42. I usually go 32-36 at most 40. should I go get them checked or just wait it out? Thank you
