Crazy Question (no laughing) ;)

Lindsay • Baby #4 on the way!
So, I just weaned my toddler in late Oct 2013. We've been TTC since. I'm pretty sure this is the first month I've ovulated since. (First PPC was 1/2/14). Anyways, I noticed prominent blue veins last night on my breasts. They're occasionally tender, throbbing off and on. Don't remember this with my DD but that was over 2 years ago. I'm 6dpo. Early preg sign? Or am I grasping at straws? Really hoping this is our month. We've wanted baby #3 since Sept 2013. Any advice?
