You seem up on your nutrition and training. I'd still like to see your daily diet just to be sure, as well as your cardio and training regime.
Birth control is fine to be on while cycling anavar, Winstrol (winny), primo. Some ladies believe it hinders them because of the estrogen. However unless you are doing bodybuilding and need to get extremely lean I wouldn't worry. This time stay on it and see how things go. It shouldn't affect you too much.
If you liked Winstrol (winny) and had no problems do a winstrol cycle again. What was your dose originally and did you get any unwanted side effects beside the initial bloating?
Anavar is the ideal for women. Fairly inexpensive, easy to come by and has the fewest side effects for most. Start at 5mg and cycle for 6-12 weeks.
Primo is hard to come by. At least "real" primo. There is a ton of fake primo out there. It is also a good one for ladies.
Now bcs....is that birth control or something else. The first part of your post confuses me a little bit.
Also what do you want to compete in? Bodybuilding? Figure? Fitness? Bikini?
