Hi Holly, massive congratulations!
I was 17 when I fell pregnant and 18 when I gave birth to my daughter.
I'm 33 now and just gave birth to my second baby, 5 months ago.
Having a child so young did bring it's challenges, but there are challenges no matter how old you are when you have a baby.
I was able to go to uni, thanks to the support of my mum. She worked nights so was able to take my daughter to and pick her up from nursery.
I was a single parent but always made sure I made it easy for her dad to be in her life and we have a decent enough relationship as her parents.
Being on my own was bloody tough, I won't lie, but my daughter is almost 15 now and we have the most amazing relationship.
I've never once regretted a second of my daughter's life and I'm so proud to say she's my daughter.
I will be honest and say I'm much more relaxed this time around but then, I'm not trying to bring up a baby while continuing my education and establishing my career. All of which was hard work but definitely worth it.
You won't and shouldn't need to put your plans on hold. Life is just different with a baby and you'll need to consider the best path for you.
Babies do put even the strongest partnerships to the test and you need to work together to get through the really hard times. I look back now and see that wasn't something my ex and I had the capability to understand and do, but that doesn't mean all young couples aren't capable of it.
You were definitely right in making an appointment to see your GP. I'd suggest either calling your surgery or asking when you attend to see the GP if they have a community midwife at the surgery and asking to refer yourself if there is.
Good luck and enjoy your baby!
