Sorry for my ignorance but what is a BFP?

Hello, I am new to this site and would like to know if anyone has any experience of the Winterborne Clinic in Dorchester? I have been trying now for 3 years and next step is IVF which I know absolutely bugger all about. This clinic is the nearest to be (I'm in Bournemouth) and I would be interested ...

No periods has been a common thing in my life - now 31 and haven't had regular periods EVER !! Sometimes I have gone 3-4 months but more often it is every 2 months.

On hormone injections now which stimulate ovaries and generally I am having periods every 28 -30 days now.

Next step for me is IVF ...

Deffo socks on - I'm usually in and out in 2 minutes then!
