Advice please! Pregnant or not?

Tiffany
My last period was August 24th 2015 and I haven't had a period or anything since then. Me and my fiance are trying to conceive so I've taken plenty of home pt but they all come out negative. It's so frustrating cause I have pregnancy symptoms and this would be my second pregnancy, I have a 4 year old, and I haven't seen a doctor yet so I really wanna know if anyone has gone threw this, I read a couple of posts from everywhere about women experiencing the same thing but they don't give a update so I really need some opinions or thoughts.
