hi, im a little worried today as i dont have much tenderness. I started wonderup on the 31st of jan (day 17) along with massages, i had tenderness almost immediately within a few days which stayed every day up until today, i also got some fullness. Is it normal to be quite tender and then almost nothing? or does it come and go?

That is normal, you are lucky to have felt so much tenderness within one month. It generally comes and goes with your hormone levels rising and falling during your cycle.
If you feel the tenderness doesnt return at all in the next two months you may want to lower or up your dosage, it is all figuring out how much your body actually needs for growth.

thanks for your reply Lisa :) all the tenderness came back yesterday and i still have it today im pleased to say. (this is prob the only time i look forward to pain lol). I was worried that i had stalled or something but i seem to be fine now and have 1cm increase! altho could just be swelling of course.
