Your higher pH may have been because AF was due. pH can be a finicky thing.
Also, sometimes your body needs time to adjust to the Acijel - if it sees the Acijel as a "foreign invader" it may produce higher pH mucus, trying to wash it away. I actually think you may be using too much Acijel. It may have caused a bit of inflammation that raised your pH.
Please read the Rephresh/Replens/Acijel essay if you haven't already, it has more about doses and how often you might want to use these products.

Your DH does have high pH THIS one time you tested him. Check him a few more times, he may have just eaten something that made his pH go up. IF it stays high, he may want to see a doctor just to rule out any infection (some kinds of infections can cause high pH in the semen). If he gets a clean bill of health, give him some baby aspirin and have him drink aspartame and it should go down.
Have you lost any weight? My pH dropped very quickly just from losing weight with no other changes (although it didn't help me conceive a girl).
