7dpo maybe symptoms ?

Perimeter of breasts slightly tender, gas, had a little bit of cramping around 12am but didn’t last long at all like 10 minutes maybe had a head ache yesterday and my nose is stuffy but no cold symptoms had a higher temp last night but back to normal today. Fatigued but I’m a nurse so being tired is a way of life . And yes even nurses needed advice they don’t teach you this stuff. 😂This could also all be in my head lol 2WW plays tricks on you. Anyone have any input ?
