Tonight or tomorrow morning?

Quick question: my husband and I are ttc a girl we have been doing the every four days method along with me doing OPKs. We bd last Monday, and Friday. This morning, Sunday the OPK was faint, and this evening it looks pretty close to positive. Should I wait until Monday morning to keep closer with the every four days or bd tonight and pray for pink? Though I'll be praying for pink regardless...

Thanks for everyone's help!!

Just to give a little update:

I took an OPK this morning and it was still positive, so we DTD.

:luck:Now for the 2WW! Pink Prayers are always welcomed!:fx:

Sorry I am only just now catching up to this - whatever you did was the right thing to do.

Under normal circumstances I would recommend sticking to the e4d pattern.
