No, it's a great age to be pregnant.
I had two in my early 20s. No regrets whatsover, I was full of energy, loved playing with them, chasing them round the soft play was a breeze, I adapted really quickly to parenthood (something I see my friends becoming mums later struggle with). They're 16 and 18 now, absolutely thriving in education, lovely polite and respectful young people. Me and their father are still going strong. Not that I'd judge parents who separate, but I did have a couple of people ask "are you still with the dad" when they were little and I did feel like I wouldn't have got that question if I'd been older, in fact I had my third in my mid 30s and no one has asked me that question this time round.
