Any advice needed!

My husband and I have been trying to conceive for 6 months now. My period is due today but always spots several days before it actually arrives (which hasn't happened). The last 2 weeks I have had awful nausea on and off along with sore boobs dizziness and hot flashes..

Do you think it's too early to be seeing signs of pregnancy?

Any help would be greatly appreciated, i an going crazy!
