9 days pp.

During my pregnancy with my daughter my ob kept asking "are you sure that you want your tubes tied? Because I'll ask 10 thousand more times" I kept saying yes like I was so freaking sure I have 4 kids now. And after seeing my daughter after she was born made me cry. Idk why but I feel as if I can't go through the decision now.... Almost already did the deed but my husband even said nope no more. But deep down he knows that he wants one more. Did anyone feel like this because know that once you get your tubes tied it's the last positive tests, it's the last ultrasounds the last morning sickness's. The LAST everything? I can't pull through with my decision. My husband is older then me and I'm only 32. And my ob said to me "yup I heard that before" not being harsh or anything. But can someone like explain this to me???!!! 😭😭😭
