Clomid

Hello ladies I was wondering if any of you that are on clomid have had any problems with either deep vein thrombosis or pulmonary embolism. I have been diagnosed with PCOS and my Dr has me on metformin but I'm still not ovulating like I should and I was going to ask her about clomid but I have a history of 1 pulmonary embolism and 4 deep vein thrombosis and I only get them when I am on something that has to do with me starting my period. I can't be in birth control due to having to many blood clots. If you can tell me about your experience it would be very helpful. Thanks for reading and baby dust to you all.
