Over emotional since TTC

Technically me and the OH have been trying for about 6 months now (unprotected sex), but we only started TTC properly about a month ago (getting this app, keeping better track of my cycle, being healthier with food/drink etc.) But in those 6 months I've found I'm increasingly over emotional. I will cry over silly little things, from stories about homeless animals, to hearing about acts of kindness from strangers. It's even worse when I look for tips to conceive or hear about friends/family (even strangers) falling pregnant. Is this natural and what can I do about it?
