<human>: Can you give me the gist of the text in a nutshell?

Hey, sorry if this isn't an appropriate post but I've been lurking for a while now. First thing first, I'm not the one maybe pregnant, but my fiancé seems to be having some symptoms.

So my fiancé and I had an unplanned baby girl 9 months ago and right afterwards she got an IUD put in and I have always worn condoms, which I/we don't believe have broke. 

Over the past few days/week she has been getting really bloated and her stomach has been really hard. Also she has been having really bad back pain for about a month, which her doctor and chiropractor cannot diagnose what's wrong.

I am freaking out since she is at work and wants to take a test after work and I just really need to tell someone and don't know who to go to, so I turn to anonymous internet people!(no offense)

I love my baby girl, but we don't want any more for about 5 years when we're on our feet and I'm out of school, I don't know how we would get through having a 1.5 year old and a newborn.
<bot>: fiancé and I have very protected sex, but she is getting symptoms of pregnancy and don't now who to turn to.
