Worried 🤦🏽‍♀️

So I am 3 weeks post partum via c section and me and my boyfriend did a dumb dumb and had sex unprotected. I’m not on birth control and he did finish inside of me multiple times. I know I feel so dumb and I’m worried I’m pregnant again 😭🤦🏽‍♀️ I definitely want more kids but I know it can be extremely difficult not only having them so close but getting pregnant too soon after delivery is obviously a risk for my body and for baby. 😪 I feel so stupid have any other moms “slipped up” and gotten pregnant this soon after delivery. If so how did the pregnancy go.
