Not Sure if Pregnant

Confused if pregnant or not. I had multiple miscarriages in the past. May times pa na nagpa ultrasound ako yet walang makita pero positive naman sa pregnancy test. This is the reason I hesitate going to Sono for ultrasound early. Ngayon po nagka period ako. (TMI) Pag wipe ko may pink blood. So naglagay ako ng napkin pero after non, brown streak lang then wala na. Nag PT ako pero parang faint positive yung result. Im thinking too early for PT. May same po bang experience sakin and pregnant po pala talaga? I’ll wait another week pa po kasi before visiting OB. Thank you.
