People don’t suspect I have kids until I tell them and when I do they get very surprised

I know my very inadequate looks can really throw people off and make them assume I get no love at all from the opposite sex, but this is really irritating me. I feel like as a mom, I shouldn’t be reduced to a liar about my own child. Why would I lie about having a child only because you don’t believe my ugly ass could even get a partner let alone get pregnant by said partner?
