I think it would be too soon for pregnancy symptoms at this stage anyway... i'm not sure about you, but i always get bigger breasts before AF. It could be implantation bleeding.. But just because you and your husband 'tried' a few more times than usual this month can actually lessen the chances (unlike comman belief) as the sperm isn't as high in quality.

But i have all my fingers crossed for you, and i hope you get a BFP very soon!
