What do you say when someone tells you that you are pregnant

Ask them when they tested your blood and/or pee? Then tell them not to be so bloody rude and assuming.
Sorry, but I used to get this a lot and hubby and I are unable to have children, so I tend to get very angry at people for it these days. But then we have been married 24 years this year and it gets very old very fast and also heart breaking having to explain all the time.

"No, I'm not pregnant. I'm just fat."
^ This is my standard reply, and it usually embarrasses the heck out of people for asking.

That's happened to me before. She was pregnant herself so I feel like she was just trying to find people with similarities. We seem to see things we want to. She said "oh, you're pregnant too?" And I said "haha maybe" It honestly didnt bother me. She wasn't trying to be mean or anything. I have a belly, I know that and that's OK. I've accepted my body, know where I want to go, and am loving it as I work my way there. It housed two beautiful children. Now, if she had been saying it maliciously, I may have felt differently.

Say in an extremely enthusiastic tone “Thank you so much for asking! Let me show you the ultrasound picture!” Then show them this...

Hopefully they get the message and don’t ask again!

It happened. Right before a holiday meal as I walked in the house. From one of my dh's family who patted my stomach while saying it. I had thought I looked okay that day.
I just said I wasn't pregnant and she apologized. We were both embarrased and awkward. I felt like leaving and crying the rest of the day but did not. I ate much less that day and talked much less.
I tried to be understanding. My dd was young so people probably expected us to have another child soon. I do carry my weight like a pregnant woman. A lot of people are overweight and that is just how my body gets. I get to have thinner legs, hips and arms. She wasn't trying to be mean or hurt me. She just made a mistake. I can understand but it still hurt for quite awhile.
I think I eventually just embraced it a bit and got some maternity pants which fit my body type great and looked better than regular clothes that sagged everywhere but the waist. I stopped wearing so much black to try to look thinner and got colorful clothes I liked. In a way maybe it was freeing me from being so self concious or caring what others thought of my body shape.
Still pursued losing weight for my health.

This was one of the things that hurt me the most, to be honest. All throughout my weight loss phase, people were constantly asking me when my baby was due. I was trying so hard to lose weight and get in shape and it was such a blow when people said this. Friends gossiped about it behind my back. The worst was after having family pictures taken, and a family member immediately messaged me asking when I was due. I was so happy with how those pictures came out and it made me feel so bad. My baby was 5 months old. I wasn't pregnant.

I have diastasis recti, so even at a normal weight I have to be careful with my posture. I also have fibroids and cysts, so the bloating from that makes it even worse. I once had an Ikea saleswoman ask my 9 year old daughter if I was having a girl or boy baby. My daughter told her that her dad had a vasectomy and we weren't having anymore children 😂 The saleswoman couldn't run away fast enough.

Unless you see a baby physically crowning, please don't comment on a woman's appearance or assume she's pregnant.
