So confused

Carol

I went to doctor on cycle day 3 an they told me i had a cyst because my egg didnt release last month. My period usually last 3 days. On night 3 i had really bad lower back pain an cramps an started bleeding again for another day. Period finally stopped. 2 days later after intercourse i had light spotting. Hoping the cyst ruptured but not sure. Doctor wanted to give birth control but i refused. Trying home remedies. Any advice?
