Baby fever .... looking for support

Hi ladies! I’m new to this app. I’m struggling right now because I have 2 amazing, beautiful little girls (4yrs & 2yrs) who are my entire world. My issue now is that I’ve been holding onto the idea of having another (going for that boy) but my husband (who’s 6 years older than me) isn’t too sure. He thinks that it would be smarter to stick with the two children financially and mentally. From my point of view, I feel like I am supposed to have 3 children. I had a miscarriage between my girls and feel like something is still missing in my life because of that. I hope this doesn’t sound selfish as there are so many strong, amazing women who have dealt with multiple losses and aren’t as fortunate as I am to have my girls. I guess it’s just a mental part of me can’t help but feel like that miscarriage was my boy. I’m getting older and worry that I’m running out of time. My family tells me I don’t need anymore but I’m the only one with children and can’t explain to them the feeling of emptiness even though my life is so full. Am I being ridiculous??? Thank you for not being mean if you choose to respond. I’ve been really struggling with this and it was so refreshing seeing All the happy pregnancy announcements as I know what an amazing feeling it is when it happens!!! Thanks for your support as I really feel like I don’t have anyone who understands my internal struggle right now.
