Anyone diagnosed with Placenta previa?

Well early this morning I had blood and a clot come out..went to the ER and thank God the baby is alright, strong heartbeat...unfortunately I was diagnosed with placenta previa... Now, per dr. orders, no sex, no lifting or bending or anything strenuous... I was told since im only 18weeks it is possible for the placenta to moveor shift later in the pregnancy so that I can avoid a c-section...Anyways, just a little freaked out...thankfully , even though my husband is out of town for work, he is very supportive and understanding... And I also have my wonderful parents helping me out with my two girls and dogs...
