Bleeding at 2nd trimester

Anyone here po na nag bleeding din ng 2nd trimester pero ok naman si baby? I have SCH nung 1st trimester ko na nag clear naman nung 13th week tas nawala spotting for 2 weeks then nung 16 weeks ko nag bleeding na naman ako pero tumigil naman agad after ko inuman ng gamot. Medyo napa praning na kse ko. Need some advise para kumalma isip ko. Salamat.
