Birth control

At age 14 I was diagnosed with endometriosis and doctors placed me on birth control to help with the pain I was having. At age 18 after trying just about all forms of birth control I decided that the pain I experienced was better than feeling like I did on birth control. When on it I was always having hot/cold spells, nausea all day long, upset stomach, bloating and migraines. With in 2 months after stopping it all symptoms disappeared. At age 22 I fell pregnant only to miscarry weeks later. After the miscarriage bleeding stopped I was assuming my period would return to normal the next month only it never showed. Yes I was pregnant again, carried my baby boy to full term and he's happy and healthy. Question is has anyone else experienced these symptoms while on birth control??? Sorry this so long and a bit off subject
