Ttc baby#2

I have been ttc with my fiancé for close to 2 yrs now. I am 34 and have a 14 year old daughter. I am keeping my fingers crossed and hoping that this is my month. Af is due Saturday. I have been having some weird symptoms like soreness under ribs, heightened sense of smell, and diarrhea(not to be gross) don't want to get my hopes up though because some symptoms that I have are the ones that I get before af.
