blood clots after delivery

Kirsten • married 6 years to my best friend! mommy to two beautiful little girls and handsome little boy! 💜💙💜 God is good!
so i just had my baby 3 weeks ago. she was 15 weeks early due to severe preeclampsia. I am now back in the hospital due to a blood clot in my lung. the doc says that i will likely be on a blood thinner for quite awhile and getting weekly blood tests. has anybody else experienced this?
