A woman welcomed twins after a one-night stand, as the morning-after pill didn’t work for a little-known reason.
Holly Firth, 29, engaged in a romantic liaison with a fellow guest at a family friend’s wedding on July 9, 2024.
The bank worker, from Ayrshire, Scotland, went to get the morning-after pill the next day and ‘thought nothing more of it’ until she began experiencing pregnancy symptoms.
Two weeks after the one-night stand, Firth began feeling nauseous at the smell of the air freshener at her office.
This prompted her to take a pregnancy test, and on August 7, 2024, she discovered she was expecting.
“When I found out I was pregnant, I burst into tears. It was just utter shock,” Firth recalled.
“Obviously, that came as a shock – I was single and I didn’t know the guy.”
In the same week Firth learned she was pregnant, she went to a six-week scan appointment and was told she was expecting one baby.
However, her eight-week scan revealed she was actually pregnant with twins.
The mom said: “I remember going out for dinner that night with my mum and dad and saying to them that it meant double the love.
“I knew from then that it was meant to be.”
Identical twin girls Charlotte and Rose Firth were born five weeks early via a planned C-section on February 27, 2025. Charlotte weighed 4-Ib and 12oz, and Rose weighed 4-Ib and 8oz.
Firth, who had wanted to be a mom since elementary school, said: “I wasn’t planning to get pregnant – I’d been single for four years.
“I’d been single for so long that I genuinely didn’t think that I was going to have kids.
“I wouldn’t have it any other way – regardless of if it was from a one-night stand or from a relationship – I’ve got the girls, and I wouldn’t have them if it didn’t happen.
“I remember seeing them for the first time and feeling such an amount of love that I’d never felt before in my entire life.”
Firth is raising the girls as a single mom, as their father has chosen to have no involvement.
“I have said to the dad that the door will always be open for him, if he ever wants it,” the 29-year-old shared.
“He hasn’t used it yet, but if the girls ever want to reach out, there will be ways of doing that.”
Firth discovered that the morning-after pill was ineffective because she had already ovulated.
“I’ve used the morning-after pill before and it’s always worked, so I assumed it would be fine this time too,” she said.
“However, I later learned that it doesn’t work if ovulation has already occurred—something they didn’t mention when I picked it up.
“My period was actually due the day after the wedding, so I know I had already ovulated. I believe that’s why it failed.”
According to Healthline, “It can be difficult to know exactly when you’re ovulating, which makes it hard to tell whether Plan B or other emergency contraceptive pills will be effective.
“If you’ve taken Plan B and aren’t sure if it worked, it’s a good idea to take a pregnancy test three weeks later to be certain.”
