Need someone to talk to

I know this hasn't been long but I've been ttc for 2 months now and I just got my period today.. I'm feeling sensitive and upset I know it's only been 2 months and I know there's women out there who have been trying for years, but it's still frustrating and makes you sad no matter how long you've been trying, my SO wants a baby as well and we would both be happy to have another child my oldest is 4 this would be our second, but he's not upset if I get my period when I tell him I just started my period he just says oh okay.. He doesn't seem bothered one bit by it so I keep to myself how upset I am about it.
