Ttc worries pls read.

Ladies I'm about to ttc in a week. But here's the thing I've waited for this time for what feels like forever(we waited for personal reasons). But all this week during my period I cry which is not normal for me. I don't know if it's the excitement of trying finally, our trip, me worried we won't get pregnant quickly like I thought( I know it takes 6-12 months), or everyone / everywhere I look someone is pregnant and I want that and feel sad. Pls ladies tell me this is normal and some of it is period hormones. I'm to the point I don't want to go around family and then have to explain why I'm sad bc I can't figure it out myself.
