Don't you find 'preg-coming out' embarrassing?

I'm posting this in the 'Life & Marriage' section because I'm curious about the opinions of people in my parents' age group.

I'm a woman in my early 20s, and I'm worried that if I get married and get pregnant later, telling my parents will be way too embarrassing...

I know having a baby is a blessing, but when I actually think about telling people I'm pregnant... I can't shake the feeling that it's like advertising that I 'did it' T_T. No matter how much I think about it, it's just so cringe.

I don't know how to get rid of these thoughts... The act itself is just so dirty to me T_T. Since ultrasound photos are basically the byproduct of that act, I'd be so embarrassed to show them to my parents or friends...

+ When I see my boss's son at my part-time job, I can't help but think, 'The boss and his wife must've done it,' and it feels so gross. I think babies themselves are cute, but to me, sex only looks like an act of satisfying sexual urges, so I can't relate to the whole 'sacred' thing at all T_T. It just feels like an excuse to satisfy libido... Honestly, even thinking about my parents doing it—I'm sorry, but it's a bit gross.
