I'm 25 weeks pregnant and my first daughter was born at 32 weeks. As I head towards the 30 week mark I'd love some reassurance and/or warning if an early birth might happen again - I've heard about the Fetal Fibronectin (fFN) test, but it's not something the NHS give as a matter of course (I've asked!) so I'm looking to get it done privately, though I'm finding my options are quite limited. Anyone had any experience of having this done privately and would you recommend it? Any suggestions on where to get it done too would be great - I'm between London and Cambridge but am happy to travel.
