Anxious

I’m beyond nervous and anxious. I’m only three weeks and a few days... I have so far to go. Now I’m wondering am I meant for motherhood. When do I tell my own mother that we’re adding to the family? How do I know if I’m overworking my body? How do I know I haven’t done anything wrong to my body. Did my embryo stick? Is my baby going to be healthy. It’s incredible how my moods have already changed. I’m on the verge of crying just thinking about things. My first appointment isn’t for another two weeks. I keep getting light cramps and I hope they’re normal. All the things I thought I knew..... I don’t know and I’m so overwhelmed
