:yeahthat:

Mine dropped over three tests, but each test was at different times of day & varying stages or hunger (one, I had just eaten, the others were either famished, or ate ~2hours before).

Your P4 levels will fluctuate throughout the day, and if you eaten.

I was put on pessaries, but there's a lot of contention about whether they help or not. FS gave them to me, but my local OB said they're only there to make the mother feel more secure. I don't think I needed them, but they were worried as I was going overseas for 2 weeks, and may not have been able to get them if I started spotting.
