I had a very complicated pregnancy which ended on 30th April this year. I gave birth to twin girls, but sadly neither survived. The waters around twin 1 had broken at 14+5 weeks.
I saw my consultant on 4th August for a review appointment. I told him we were TTC again, and in fact, I was waiting for either my period or a positive pregnancy test then. He took some swabs for infection and chlamydia (the latter exceptionally unlikely, but can be a cause of premature rupture of membranes, so I wanted to be tested on the off chance as I know it can be symtomless for absolutely years). We both felt this would rule things out and ease my worry if I were pregnant or to get pregnant. The consultant said I would recieve the results in a couple of weeks.
Well, it is now three weeks later and still no results. I rang the consultant's secretary to chase up this morning, and apparently one lot of results are back, one aren't. The consultant is away until next week, so I won't here back until then.
I do appreciate that he has to have his holidays, but if I have an infection or something it could potentially end my pregnancy when it is something easily treated. I'm also wondering if the swabs are taking so long to come back, does that mean there is something wrong? The only time previous swabs have taken this long is when they were positive. 
AIBU to expect to know what is going on and recieve the appropriate treatment ASAP?
