@Tanej78 I just looked through the history of mine and gelati's P4. During the official BT, Gelati's was around 60s for her successful cycle. Mine was around 100. But my P4 did drop to 36 and FS told me to have 2 pessaries a day. He likes it to be above 30. And after reading through a few pages of the thread back in February, I realised p4 can go up and down during the day. It is a guidance but not the only factor. Are you having another BT to check p4 in a couple of days? Try not to stress because I think p4 above 30 is still good. Some pregnant women never have high p4.
