Delay spray/creams, for use while trying to get pregnant and during.

Can anyone recommend a delay spray/cream that can be used while trying and during pregnancy?

We currently use http://www.lovehoney.co.uk/product.cfm?p=27146 but it says not to use when pregnant so have stopped using it.

I have tried the training techniques but for me it's over sensitivity. We have rings they do work but not as well as the spray.

Thanks
