I’m following Vedic system only except put incorrect time used Pm instead of AM. Yes your 7th house is Gemini and ruled by Mercury. Lagan is Sagittarius. Now we see that Ketu and Mars are in the 7th house which is not good. Mars in 7th house makes you manglik. Ketu wherever is posited will suppress good effects of that house. Therefore marriage should be done with proper matching of the horoscope. Also the chances of love marriage are very much there.
