AF due 21st September. Symptom spotting is driving me crazy.

Chelsea
Me and my husband are TTC our first together, he has a 5 yr old from a past relationship. I am 8 dpo and am having some cramping and twinges in my pelvic area for the past few days. On and off nausea and really bad wind, which is really usual for me. Also, the last few days i have been waking up with a really bungled up nose and have to blow my nose loads. I read that some of this could be early signs but am too scared to get my hopes us. Does this sound like I could be pregnant or is my body just tricking me? Really want this to be the month! X
