AF NOT due 3/14! 8dpo! Symptoms here!

Ok! AF is not due 3/14! I got a positive digital smiley face OPK 2/28! Now the wait. I could test as early as 3/9 but I'm nervous! This is our 5th cycle trying for baby #2! 
I'm currently 8dpo 
Symptoms this time that I haven't had previous months: 
-Diarrhea (I'm on an antibiotic though)
-Dizzy spells when standing up quickly started 6dpo 
-Sharp shooting lightening bolt vaginal pains with stretching pulling feeling in uterus at 6dpo-8dpo 
Anyone else?
