Feeling an emotional wreck

I’ve never wrote on here before but just need someone to talk to 😭 been ttc for about 5 months now. Aunt Flo hasn’t come this month yet 🤞🏻 she doesn’t come at all but finding hard to conceive as my husband works away a lot!! It’s getting me down now and I know a lot of people try for a lot longer then us but it’s just got to me this as my sister has just announced she is pregnant! I haven’t told any of the family we are trying but they keep saying I think it’s time for my little girl to have a sibling and I feel like I’m just screaming inside saying IM TRYING!!! But I don’t want them to keep putting pressure on us! I really don’t know what to do?!?! 😭😭😭
