A mum claims her contraceptive implant has told her 'it's safe to have sex again' - by leaving a four inch penis-shaped bruise on her arm.
Sarah Waugh, 24, discovered the mark after removing the bandages from her left arm.
And she was left in hysterics after her husband Chris Waugh, 29, quickly pointed out the rude resemblance.
She had the contraceptive implant injected into her upper arm last month after the couple agreed their three-year-old son Joel was enough for them.
Sarah immediately noticed a small bruise start to appear on her arm and was told to keep the dressings on for the next five days.
Over the next few days the bruising expanded across her arm and slowly started to emerge from under the bandages.
But she had no idea what shape it was taking until last Sunday when she carefully soaked off the dressings.
She held up her arm to show warehouse manager Chris she had managed to remove them - only for him to burst out laughing.
Sarah thought he was winding her up so took a photo and noticed the distinct shape of testicles and a penis extending four inches up her inner arm.
Full time mum Sarah, of Dundee, Scotland, said: "The bruise is definitely telling me it’s okay to have sex now and not get pregnant.
"My husband was the one to comment it looked like a penis when I lifted my arm to show him I’d finally got the dressing off.
"I didn’t believe him but took a photo to see it myself and low and behold there it was. It's so so funny.
"It looks even worse now as the top is going darker it looks more like a head now.”
She added: “My friends have said it’s so willy like they can’t actually stop laughing. So many people have had a good laugh at it.
"I’m showing it off to everyone as it’s so hilarious.
"I did get a lot of shocked reactions to the size of the bruise because it was bigger than the bandaged area."
Sarah went on "I don't usually bruise more than the average person but I was warned it would bruise.
"It's only sore when pressed and it didn't hurt while it was being done except from a little nipping when the anaesthetic was injected."
