I just found out I have BV

Am 25 years old never had bv I am also pregnant

I had no symptoms of bv not foul smell or burning well peeing

they give me metronidazole vag gel for 5 days l I wiped myself and noticed that there was a clump of discharge that was slightly yellowish green  is that normal with bv? Or some I get tested again side notes ( when I got tested for sti and std everywhere came back negative but my urine had white cells in it so I when back to do a swap and if came back as bv )

Added a picture
