Boyfriends sperm was yellow when it came out of me after sex..

It was heavier looking too. It’s came out of me after sex.. and it dropped straight to the toilet. And it was a darker yellow. I just started my period today though. Could it have been mixed with my blood?

I have normal discharge. Not itching down below. And the only thing I been having is a strong smell. I think I have BV.. and I’m literally on my way to the drs rightnow.

And sorry in advance, I meant to post this is health and lifestyle. But I hit the wrong group.

Edit*** it was BV.
