Hello,

Thanks for your consult at DoctorSpring.com.

Prometrium ( progesterone ) DOES have the unfortunate side effect of upping your risk significantly of developing blood clots and bruises, particularly if you already have had a history or risk in the past. The bruises can definitely be caused by prometrium.

However, other causes also should be ruled out - a blood count to know the platelet levels, your liver function profile, blood clotting profile etc.
You should be concerned, and should be seeing your doctor right away.

Other causes include - thrombocytopenia ( low platelet count ), deranged bleeding profile, deranged liver function tests so these should be excluded by the tests mentioned above.

Also, if other reasons are ruled out, these supplements should be stopped, and alternatives instituted ( lower dosage, alternate day dosing, dosing with monitoring of your clotting profile - these are some options).

All the best.
Please feel free to ask for further clarifications.
