lauren congrats on the great beta... oh well i was diagnosed with placenta previa at 14 weeks and was cause of my spotting in first trimester. then they found planceta vasa where a blood vessel comes off the placenta and causes big probs. i will get a c-section no later than 36 weeks. so i can deliver anywhere between 28-36 weeks depending on how bad my bleeding is at that time. it really doesnt cause a risk till 28 weeks. but I am showng bad signs starting at 14 weeks. go figure. if u are preg with twins i wouldnt rule out a loss twin as of yet bleeding is very common this early on especially in twin preg you might even have a minor subchrionic bleed which is really nothing to worry about. congrats on the beta again it sounds great!
So, are you on bed rest or limited activity? Best of luck. There is so much to worry about every step of the way!
