    I’m 16 weeks, and I had my monthly check up Monday. My doc brought in a pocket ultrasound, and it sure looks like we’re having a boy. I have 3 daughters so I’m hoping what I seen was correct. Doc says looks like I can throw out all my 2 year olds baby clothes now. But I’ve already donated them along time ago.

    We are having a boy. This will be our fourth boy. We were kinda hoping for a girl for our last pregnancy, cause I’m having a tubal. As long as he’s healthy we will show him nothing but love.

    The first pregnancies are always scary. Haha. Especially if you’re only 18.

    • Avatar of LeilanyMamoe LeilanyMamoe says:

      Hang in there, Melanie! I was pregnant at 18, so I know the fear. I’m 31 now with an ‘oops’ pregnancy and I’m probably more scared! Lol. It’s all worth it and part of His plan! Good luck.

  14. due October 2014 first baby and super nervous!!

    I’m 29 weeks and due in May 10th. This is my first child and I am having a boy.

  17. Avatar of Amber Amber says:

    I was hoping for a girl but your gender predictor says a boy. I have 1 boy already. They are a handful!! My due date according to your calculator is Sept 16th 2014, which I found odd because when I entered my last menstrual date, you automatically knew the exact day I conceived. I was impressed by that. Also you estimated my fetal age to be 10 weeks and 3 days, whereas I thought I was closer to 7 weeks (lol)… Let’s see if you were right about the gender! Thanks!

    its my first baby am only 14 weeks and 1 day my stomach look like am 6 month i don’t know am scare a lot of people tell me my stomach look weird i don’t know if i might be more weeks than am expecting or i might having twinsaim so scared what you guys think?

    • Avatar of Megan KlayEditor Megan Klay says:

      Hi Marie – Have you seen a doctor yet? Typically they would done an ultrasound by 14 weeks and would have spotted two heartbeats rather than one to tell you you were having twins. Some women’s baby bumps just appear larger than others. It could even be a lot of water weight as women tend to retain more water in general, but especially when pregnant. If you have concerns, discuss them with your doctor. Best wishes!
