32 weeks with twins

I'm 22 and this is my 4th pregnancy. I have 3 girls (aged 1, 3 and 6) and I am 32 weeks pregnant with twin girls! I can't believe I am going to have 5 girls in just a few weeks. I am married to my husband of 2 years but we met when I was 15 and he was 18. I got pregnant not long after we had been together and had my first baby at 16. Although I had a baby I still managed to go to university and graduated last year. I started as a school teacher but am now on maternity leave. My husband is in the army and has been for 6 years.
