I am so sorry about your m/c. Your hcg
is coming down slowly hence a positive hpt that you saw. When your hcg
is low enough you will get AF and that's how you will know your cycle started. I don't think there is a home remedy to re-start your cycle. You just have to wait for your hcg levels to fall. Again, I am so sorry you are going through this terrible experience.
sorry about the weight gain. Lupron gives so many people bad side-effects.
