Tried for baby now serious doubt!!!

Ok so I actually can’t even believe that I am writing this. But I need to talk to someone or something.

I am currently 13 weeks and 1 day pregnant with our fourth baby. Which we tried to conceive and was the only baby we ever tried for (not making the others any less special we adore each and every one of our beautiful children) we caught pregnant in the first cycle of trying, I was over the moon.

I started buying things super early, without even seeing a scan to confirm. By buying things I mean pram, car seat?? I can’t help but think I was over compensating for something?? What? I don’t know!

I have been having doubts lately, will I cope? Is this what I want? What if I resent the baby when it’s born?

I don’t even know why I am feeling like this and I feel so crappy about it when I have friends that can’t even have children and I have a blessing of being on my fourth and I feel like this. What is wrong with me?

Need a bit of advice please guys!!
