Pregnant po ba?

Nalilito po kasi ako if positive ba talaga since faint lines po yung iba. But yung 24 and 25 po was before my period. Yung isang "Nov 8, 9am" lang po ang tanging nag negative but that was after I ate breakfast and nag water. The rest po was faint lines and Nov 5 was clear lines po na positive. And spotting rin po ako for 3 days. Need pa po ba ng blood test before OB check up or magpa check na po ako agad?
