best day ever 🤗 bucket list ✔️

Sa
So I have 2 kids one 16 months and my little one just turned 2 months today. I love them so much. Well today I also got to cross something very exciting off my bucket list 😏😒😭 A little back story first  I am 20 but people think I look 16-17 anyways.... so I am in Walmart with out my babies because I asked my mom to watch them so I can get some me time so I do all my shopping and go to self check out. OK so everyone tells me that I look 16-17 Right? so think of this  I didn't have the babies with me  and I don't have my wedding ring on and I don't look like I also had a baby because my little Lillian came a month early so and I get halfway through checking out and I feel this warm trickle very small but noticeable. I have no idea where it came from. I peed my self in the self checkout line 😰 I have never done that before. Still getting use to my postpartum body. 
HAS ANYONE ELSE PEED THEMSELVES POSTPARTUM? what can I do to help this problem?
