Hope this is it

6 days until my next cycle and my boobs are killing me. Have a tingling/burning sensation in both boobs and my breast feel heavy. My nipples are also dark. I also feel like I am coming down with a cold and am spitting a lot. I had these same symptoms with my son 5.5 years ago. We have been trying for 3 years. I got pregnant on the first try with my son so hope this is it. Fingers crossed.
