My husband wants 3 kids

We have two already 5y/o and 2y/o. He wants only three and just opened up to the idea of having a third and I want 4 lol I’ve always wanted a big family. So I’m hoping to get pregnant with twins lol!!! I have fraternal twins that runs on my dads side of the family we never really had any problems on TTC it usually takes us about 4/5 months and funny seems like we always try around the same time since I gotten pregnant both times in January 🤦🏽‍♀️! And here we go again we started around the same time but I rather get them out the way now 😂. One big birthday party for 3/4 kids and be done!! Anyways I bought fertility blend to see if it helps any 🙇🏽‍♀️🤷🏽‍♀️ maybe just speed the process. Anybody have any success stories buying the Fertility Blend??
