Question about spotting and ph

I am taking clomid so had a follicle check today (cd12). I have two follicles... 10mm and 11.5mm so I should O in another 3 or 4 days. Anyways, I just went to the bathroom and had pink on my panty liner. I assume it's from the vaginal u/s so not worried. But they want to do another u/s on cd16 which I expect will be my O day (this is when I O'd last month). If I spot again wouldn't that raise my ph? I plan to do O+12 so I'm concerned about that. Also, would they be able to see if I am O'in or finished O'ing? I think I usually O in the a.m. and my appt is at 11:30 so I may have just finished. Could be useful in pinpointing O+12, right?

Yay for those follicles!
If you worry about the pH if you spot again maybe you could use Rephresh?

I had already bought acijel before and it seems to work for me. Maybe if I use it in the morning it will help keep it down

Ugh sorry I didn't see this sooner! :/

Yes, I would just use the acijel, that will counteract any spotting.

Update us! Were they able to see what was going on with your O? (I think you mentioned this in another thread.)
