Awww Ness, bugger about the BFN. Hopefully it was just too early. Your symptoms are sounding really good, so hopefully you will still get a BFP.

I would avoid eating any soft cheeses, ham etc.... just incase and as for the pump classes personally I would avoid them as the last thing you want to do if you are pg is overheat your body as that can cause a m/c.

Good luck
