Crying??? For no reason at all....

I've been TTC and I am on day 25 of my cycle and I have been crying all day for no reason at all. Just crying. It seems so ridiculous but I can't stop. On day 21 of cycle, I had some weird lower abdomin shooting pains(not usually something that happens) but I assumed maybe those were ovulation pains? Idk. Anyone have any ideas? Could these be pregnancy symptoms? Has anyone else been really emotional before finding out they are pregnant?
