Thank you for your query.
Marginal placenta previa
is the cause for your spotting.
You need to take extra care and precautions - rest well, avoid dehydration
, avoid sexual activity, strain, jerky travelling, stress
You can still be hopeful because 90 % of placenta previa migrate upwards towards the third trimester..
Sometimes, marginal placenta previa can lead to a heavy bleeding, which is an emergency.
