Advice for a shift worker

Ph

Hello lovely ladies.

So I've been TTC for just over 3 years and I've been reading this book called 'Taking charge of you fertility (brilliant book, highly recommend it). It's manly about the 3 daily fertility signs to be aware of, one of which is BBT.

I really want to start tracking my BBT but I am do a variety of different 12 hours shifts, half of which are nights! Has anyone had any experience or got any advice to try and make this as accurate as possible??

Thank you xxx
