Oh hon, it is far too early for symptoms at 1dpo! I totally understand your desire for some though!!! It is so individual for every woman. The last time I was pregnant, I had mild AF like cramps at 4dpo and sore boobs from 4dpo on. My first pregnancy, I didn't have any symptoms until 12dpo when I was due for AF. I felt cramps and sore boobs and was convinced AF was on her way.
If it is any consolation, I'm at 7dpo and think every little thing is a symptom. I went to the gym yesterday and did some arm exercises which made my boobs hurt this morning. I have been trying to convince myself that it isn't from working out, but instead a pregnancy symptom...LOL!!
Hope you get your BFP this month!
