I had been taking Yasmin monthly for 8 months with no problems. One week I had horrible leg cramping and pains in my calf. I thought it would go away but after going to the doctor and getting an ultrasound done on my leg, it turned out to be a DVT (deep vein thrombosis). I had to go to the emergency room and be admitted for 5 days. That is also where they told me that I had 3 blood clots (Pulmonary Embolisms) in my lung. I'm only 28, healthy, nonsmoker, P.E. teacher and was diagnosed with blood clots that are from Yasmin. I have no previous health problems and no family history of blood clots. I WOULD NOT TAKE ANY HORMONES IF YOU DON"T HAVE TO!!! Yes, for some people it may not be a possibility but at least don't take Yasmin. With blood clots you can not do anything strenuous, no relaxing massages, no visits to the chiropractor, no random medication like Ibuprofen without doctors approval, no alcoholic beverages since I was on blood thinners. I was moody and miserable when this happened since I had to immediately stop taking Yasmin and was in the hospital with blood clots. Thankfully the blood clots are gone but I'm still on blood thinners and have to be very careful for the rest of my life.
