Pregnant women can apparently turn things blue.

Pregnancy causes a lot of things to happen to a women but turning objects blue with your backside usually isn’t one of the first things that comes to mind.

Apparently though, that’s just what’s been happening to one Reddit user who posted a question two days ago to the popular site with the aim to find out exactly what the heck was going on.

"Has anyone here turned their toilet seat blue?" She asks before explaining, "I just realised last night that our toilet seat is now a lovely blue/purple hue. After some googling, apparently this is something that happens to pregnant people. Please tell me I'm not alone in this?"

Strangely enough after posting the question, she was quick to discover that she wasn't the only one experiencing blue bum.

I'm nearing the end of my third pregnancy and I have to admit that after reading this thread, I'm a bit disappointed. I've experienced many things throughout my baby carrying journey but the phenomenon of turning toilet seats blue has not been one of them.

Perhaps I should be thankful.

My current bathroom can only be described as elderly floral enthusiast. It's hard to determine whether the true hero of the room is the bright rose coloured bath complete with clam shell shaped soap dish, or instead the overuse of pink floral accent tiles popular in the 1950s that have a way of making you feel hungover (despite having consumed no alcohol what so ever).

Maybe the reason I haven't experienced a change in toilet seat colour is that pregnant me subconsciously knows the blue/pink colour scheme would never work. Projectile rainbow vomit is seldom a winner on The Block bathroom reveals.

I do however have a few questions for the original Reddit poster (and the others lucky enough to have hyper colour bums).

Firstly, when we talk about your nether regions ability to up-cycle the loo, are we specifically discussing the toilet seat or the toilet rim also?

Secondly, it's been suggested by some other Reddit users that the blue colour is actually dye transfer from maternity jeans. This explanation seems plausible and probably the most logical but it does prompt one to ask why you're still wearing pants while sitting on the loo? That's not typically how it's done.

Next, I'd like to know whether this blue colour is confined only to the toilet or whether you're noticing other objects changing colour also. Is this similar to the stuff they warn you about in public pools? You know, pee in the pool and everyone will know because the water will change colour. Instead though, it's "sit here and everyone will know you're pregnant". Maybe you're right, well planned, creative pregnancy annoucements are so 2014.

One lady responding to the thread explained that while she didn't experience the magic of blue loos, she did notice that her sweat had the ability to turn her clothing pink. She also noted that she went on to have a baby girl.

I tried everything under the sun in terms of old wives tales of gender prediction but I never thought to check my pits. I don't even want to think of all the money I wasted on bi-carb, draino, Harmony tests and scans. The answer would have been right there, under my nose.

Some people have suggested that perhaps the phenomenon is due to different changes to the body chemistry when a women becomes pregnant and the interaction they have with chemicals in the toilet seat.

Mamamia Women's Network, Shelly Horton spoke to Dr.Ginni Mansberg on what pregnancy does to your bladder. Maybe they have some answers... (post continues after the video).

Did you experience anything strange like changing toilet seats while you were pregnant?
