How To Treat Ankle Swelling?

Hi I have been nauseous off and on now for weeks, dizzy, ankles swell mainly when i get hot, excessively hungry hours after eating, and just had a bloody nose, I am also tired alot, or cant sleep. I missed my period last month on the 17th of March and it is now April 5th, my last period was February 17th. I have had 4 miscarriages before, and 2 have been after i take urine tests, where the result comes out negative could I be pregnant? Could it be something hormonal?
