or you could just get him to release outside for the first 3-4 in the week, and then finish inside on the last few days around OV perhaps using the balance activ or rephresh then?
I don't think lots of EWCM necessarily matters providing the pH of the EWCM is low. The only reason it sways blue is because the pH is higher, but if that's not an issue in the first place because your body pH is lower due to the diet/supps then maybe having some low pH EWCM can help you get your pink BFP instead
