TTC symptoms.

Hi guys. Just a question. I'm not usually a emotional person but lately while watching to if there's something upsetting I I can't help but ball my eyes out. Also my breast were always sore but defiantly sore now. Any ideas I've been TTC for 18months now after comming of the injection 2 years ago. My periods are just starting to settle I hope. Also have egg white CM. Thanks :)
