Dear Lulu, I understand your fear, I know the pills today are more low-dose. Do you smoke? if not no worries, how old are you? I am sure you will not get a blood clot, that is swollen and hot to the touch and you dont have that, I do understand I worry about those kind of things too, I worry so much I think its my middle name! Let me know how you are. God bless, Debbie
