3rd pregnancy

Me and my Fiance are ttc with our 3rd child. i have started noticing some lower back pain lower abdominal pressure, nausea, fatigue and just feeling plain out funny could i be pregnant? my period isnt due till the 16th so i feel like its too early to be feeling these symptoms already! i have been preg twice with 1 miscarriage. he has a 3 year old from a previous relationship and we have a 2 year old together!

I'm going to say its probably too early to feel symptoms, however a strong ovulation can cause these symptoms as well so get to bd!!
