hi, my doctor gave me Gynest Cream, Estriol 0.01%, but when I used it eternally and externally, I had pains so I stopped it (I didn't realize it can cause cancer), then the doctor gave me Vagifem 10 micrograms but when I read the leaflet, it says it can give cancer too and it had Estadiol in it. So , I started using Replens, which is a moisture , the last 4-6 weeks. The last 2 days ive had slight cramps. Would the Replens have done this? i hope someone can help as i don't really want to take anything with hrt .
