Well, Winstrol (winny) can be a very weird drug for females. Its totally hit or miss, some girls will get that nice lean muscle with no bloat from winstrol and then you will find that there are many girls who get the exact opposite effect with winstrol. Gaining weight, excessive breaking out, bloating, I have heard this more times then not from females about winstrol.
I'd say that if you are not prepared for these kinds of sides, then definitely stop taking it. Take some time off and maybe think about using some Anavar instead. Theres no point in continuing with the cycle if you are 3.5 weeks in and not getting the desired effects, and in fact are actually getting undesired effects.
Now I do notice that you are taking such a small dosage which makes me wonder why you are so sensitive to the Winstrol (winny). I also notice that you are administering the winstrol MWF. This could be one of many triggers for the bad sides you are getting. Winstrol has a very short life in the body, to keep blood levels as constant as possible (thus, potentially avoiding some sides), you should have tried to take the Winstrol (winny) everyday. By only taking the Winstrol (winny) on MWF, your putting your body on a ride of peaks and valleys that could be avoided with everyday administration. Thats not to say that this is your answer to the bad sides, but it MAY be a factor in why the sides seem so bad.
Consider this a learning experience, you now know your body that much better.
