So I've been feeling off for a few days, that familiar MS feeling, and so I decided to do a HPT today with my out of date Lullabye Conception tests. Straight away I got a clear, strong positive. Eeek!

We have major fertility issues, so never expect to conceive without IVF, and so aren't practicising any contraception. I've been pregnant once before without IVF and that ended in an early miscarriage, so I'm not getting my hopes up.

Can anyone tell me if I am more likely to get a false positive or a false negative with an old test. (I tested about a month or two ago and I got a negative then).
