Placenta problems

Samantha

So at first I was told it was low lying placenta and now the doctor says I have vasa previa, I came up to the hospital with some spotting yesterday and the doctor has kept me in until I have no spotting for 24 hours. I was also at the hospital last week for some bleeding which was when I was told I had a low lying placenta but now it’s vasa previa. I’m only 22 weeks into this pregnancy and they’re talking about putting me on bed rest pretty much to prevent any further bleeding, I feel so scared that I’m having this much trouble in my pregnancy
