Hi and happy new year to all

I was wondering if any of you ladies could help me with a question (sorry if it's silly!!) - can you go swimming while using progesterone pessaries?
My rellies have invited themselves over for a swim this week. I will be 5 days post IUI and am using the progesterone twice a day. I'm kind of concerned that the water might wash away the progesterone and make it less effective (low progesterone is one of my problems).
Does anyone have experience with this? Should I not swim? Or wait a certain amount of time after using the progesterone? Or am I being just paranoid and shouldn't worry?

Any advice would be really appreciated
