Hi wouldloveabubba,

My last TWW was my first on prog pessaries, I had some very mild cramping but that was it, nothing like you describe. Unfortunately BFN for me. I had mild OHSS on my first IVF cycle and did have cramping like you describe, but I also had severe bloating and some weight gain (OHSS). I got a BFP that cycle ( I lost the baby at 9 weeks but we now think that may have been due to having low progesterone and not knowing about it - nothing to do with the support beforehand or the mild OHSS). Just my experiences. I think things sound promising for you.

Take care of yourself and if you are worried please see your nurses or go to the hospital.

The cramping and pinching shouldn't effect your little embie doing it's thing. Best of luck, I hope you get your BFP.
