Anything?! 13 DPO

Do y’all see anything?! I’m 13 DPO and have been experiencing, for more than a week, cramping, sore breasts (especially the right one), fatigue, and nausea, but I still don’t see it! I have a doctors appt today.. would it be worth it to go ahead and have a blood test? Ugh this is an emotional roller coaster ride!! Thoughts, please?!
