AF or early pregnancy??

My husband and I have been TTC for 6 months now - know it's not overly long, but still frustrating when AF shows up every month! The first month of trying we got pregnant, which sadly ended in a chemical. :( and now it's pretty much all I think about.

I'm currently 10dpo and have been experiencing light abdominal cramps, headaches, slight backache, a little nausea and I'm super super tired! Ive fallen asleep on the sofa every evening this past week, or had a nap despite having 12hrs+ at night - which is really unlike me. Also, I usually, without fail get really sore boobs 1-2weeks before AF is due.this time, nothing. Not even a little bit and she is due in 4 days.. any advice will be much appreciated. 👍🏼🙂
