What type of estrogen were you taking? Were you taking it orally or non-orally? Did you happen to take birth control pills or Premarin? Studies have shown that when bio-identical estradiol is taken non-orally, the risks of DVT are very low to negligible, even in predisposed individuals (with activated protein C resistance and protein C deficiency). As far as I know, spironolactone also has no effect on coagulation. Do you have a genetic mutation that makes it more likely that you get DVT, past incidences with it, what about family history, do you have diabetes?
I'm not a doctor so wouldn't be able to answer you. Best of luck.
