I started trying but now I feel like I shouldn't

I feel awful. My hubby and I have been together for 10 years and have two boys. I always wanted to try for a girl and we kept postponing due to work and family commitments. We finally started a month back and we did everything correctly. We even bd on my ovulation day to maximize the chances. Now my period is due in one week and I don't want to have a baby. I feel so bad. I don't think I am ready and I just feel overwhelmed. I'm freaking out before taking pregnancy test. It's like getting cold feet. I remember how excited I was with my first and second but this time I'm secretly hoping it doesn't happen so I can tell my husband that I don't want to try. Is that even normal?  I read so many to have just one and I feel awful. 😢😢😢
