I agree you should stop the Replens from everything I've heard about it.
The thing is: If you are really really dry up there then 1) the Vagifem isn't going to dissolve (for stuff to dissolve it requires a certain amount of liquid - that is what 'dissolving' is!) and 2) if it's not dissolving then you can't absorb it and you're not benefitting from it and will remain dry (vicious circle) and also 3) if you're really dry it's very normal to bleed tiny tiny amounts - through cracks in dry skin
I use Vagifem and I don't get any of it coming out the next day undissolved. I don't see anything at all coming out.
So here's the thing, you have to get some LIQUID up there(!) so your Vagifem can dissolve. Then you will begin to benefit from the estrogen.
I recommend you get some YES VM preloaded applicators OR you can get the big tube of YES VM and then buy vaginal applicators separately on Amazon to load up yourself. (That works out much cheaper.) There is a knack to using the vaginal applicators you buy separately and at first you will get YES VM everywhere
except up your V-J-J but you will get better at it with practice!
Squirt the YES up there any night you are not using the Vagifem, immediately before bed. On the nights you use the Vagifem, coat the outside of the applicator with some YES VM. This will help you get it up there comfortably but also give it a bit of liquid to dissolve in.
Ta da! Yes VM is natural, organic, and has no nasty chemical stuff in it like Replens. You can check it out on their website. For internal use, I use YES VM (although I don't need it anymore!) and for external, YES OB - which just works for longer on the outside because it is oil-based.
