2WW and mind games

Guys! I would really appreciate some feedback. I read some posts in which people have mentioned similar symptoms- shooting twinge in right breast, cramping lower abdomen, nausea, hot flushes coming and going, headaches, extra lethargic. I'm 4 dpo and I've never had these symptoms before. I know this is too early...Just curious if anyone else's similar symptoms amounted to something  or am I just setting myself up for disappointment 🙈
