Pre seed

Danielle
Hi all 1st time post, me and my Hubby have been trying for baby number two for two years now, I have pcos and struggled getting pregnant 1st time. I have seen quite a few posts about pre seed and a lot of people seem to be having good results, my question is I tested today and had a high ovulation reading on a ovulation test so do I use the pre seed when ovulating or not, many thanks in advance for anyone who helps me with my question xx
