Bit of a tongue twister title 
Looking for some help to make a decision, sorry its so long just thought I needed all the information in. Sorry if this is in the wrong place.
I'm currently in my last year of a degree (I'm 24, started uni late) after which I'm hoping to do my pgce primary education. This will take a year and then I'll have my nqt year and I know it's pretty full on and full time. At the moment I'm in a lovely job mornings only Monday-thursday, they're very accommodating, close knit and flexible, and most people fit it around university or family. It's a small company and the kind of place most people have been there for years and all know eachothers kids etc. I've been there two years, the pay is crap (I'm on track for a promotion in the next few months though which would bring in an extra 150 a month) but I'm happy and stable and good at my job. DP is full time and stable and happy in his job (been there 2yrs) and on track for further progression. I'm also not receiving any student loan/support so not about to get a financial wake-up call when I graduate.
The thing is I'm desperately broody and have been for over a year now. we've not been doing anything about it as we want to be in the best situation for a baby and bring them into a stable home so the plan has been finish degree, finish postgraduate, earn more money THEN ttc. However every day is worse and I'm so desperate for a baby and now I can see an opening...
I'm thinking teaching is so full on, do I really want to wait another three years only to put the baby in childcare immediately (would have only been teaching two years or so, so wouldn't take extra time out) and work 9-5 Monday to Friday? It just doesn't feel like what I want to wait years for. I could take one/two years out now before pgce and after maternity leave I could work my family friendly job mornings four days a week only, granted for a lot less pay. Dp has one weekday off a week so that would be another day not needing childcare sorted. Then once the baby is two or three I could go into pgce. This would still be hard obviously but in the alternative with doing a pgce first and ttc in say three years, I would still need to work full time with an (eg) two year old.
DPs worry is that after taking time out I might not want to go into pgce but tbh I think if I didn't want to I wouldn't, baby or not. Teaching is what I want to do and that's why I'm doing it, I started uni late and have worked hard just to get to this year so if in three years time I still want to do my pgce, I will try my hardest to do it as I am now. But I would still have a degree and still need to work full time whatever it is in, we couldn't afford for me not to.
Also, I just feel like the closer we get the further we would stretch the plan for perfection - 'we've waited three years to ttc so may as well xyz...'.
For extra backstory dp and I have been together 6 years, living together 5 and very happy. He didn't go to uni and we've been supporting ourselves and both working for these 5 years.
I suppose what I'm saying is that we're on track for a lovely future and have a plan but my heart is getting in the way, I still want to be realistic about the whole thing so I'm not letting it take over, but could this be a compromise?
Thanks if you got this far!
