i m pregnent, abt 5 weeks, i went for early ultrasound, n they found a sac but nothing yet, tld me to follow up,  which i have an ultrasound coming this thursday, however i had a misscarriage last year in july and i had another one 4 months ago, so for this time im extremly nervous, wether i will b able to have a baby full term or no, jus having mixed feeling, m tryin not to think anything negative but tht but tht tiny percent negativity jus pops up, remember me in ur prayers, hoping this time everything goes fine..
