Weird?

Alright I see some women on here that post there baby bumps(that's not the problem) and then like a couple of hours later post a pregnancy test saying "oh my god is that positive?!) and then later right just had my second ultrasound. Or are like "I'm twenty weeks today" and then post "I just found out I'm pregnant" Like within the same day all this happens. It just seems weird like they are faking it all. Anybody else see this?
