What do you think this is?

Liliana • One son 2 years and expecting baby boy on April 20,2016. Love my boys so much 😍😘❤️
It started small and now it ended up getting bigger . Everyone is telling me it's blood clots on my thigh . I called my doctor and he sent me to the hospital. My leg just started cramping and falling asleep that's when I knew something was wrong . Has anybody got this when pregnant ? I'm 27 weeks .
