could I be pregnant!? Help!

Hello all I am 29 years old married to a wonderful man and we have recently decided to start trying for baby #1! I have a cycle of 22-23 days ( short I know) it's always been that way anyway March 29th we gave it our first shot and did not use any form of bc. March 29-3rd I was ovulating on the 4th I had this very light spotting ( possible IB) now I am lighting cramping, frequently peeing and I have pretty bad headaches. It's too early to test but I'm hoping someone with this same experience can shed some light for me! Waiting is awful! Baby dust and prayers to all!!!
