High hopes, cautiously optimistic

So, today I am 10 DPO. AF is due in 4 days, May 2nd. For the past 3-4 days I have been crazy tired, have been an emotional roller coaster (everything from giddy, to irritable, to randomly crying over small things), yesterday I noticed I started getting out of breath from walking up a flight of stairs, my boobs feel a little bigger(hubby and I both noticed it) and this afternoon I have very light pink spotting. Hubby and I are so very hopeful, we weren't really trying, my fertile week fell right on the the week we got married, so like any newly weds we "celebrated".... A LOT. We are just looking for some insight, we plan on testing on Sunday morning, what do you ladies think?
