History of Blot clots in my family and over 35

I am 38 years old. I haven't been on birth control in 3 - 5 years. I have a history of blot clots in my family. I don't want to get a stroke, or have a heart attack (i am ALWAYS in the 1% category, or the exception to the exception) i have never had a blot clot. i do not have any known illnesses other than nuerocardiogenic syncope.

Should i continue to take Microgestin 1.5/30 or Loestrin 1.5/30 ... i just started yesterday.

thanks,

Christine
