No breast tenderness? Early pregnancy?

Hi. My period is currently 14 days late and I’m starting to become concerned that I could be pregnant. So far I haven’t had any breast tenderness — but I do have nausea, my legs and back are aching, I’ve been cramping since 5/14, I have a small gut & I feel hungry all the time along with mood swings. I had unprotected sex while I was ovulating 5/11-51/13 so I should be anywhere from 4-6 weeks right now. I do have breast aches, pains and sharp pains that are brief however they aren’t lingering and I don’t notice my breast getting any bigger. Is this normal?
