is this a myth?

so about two days ago I went to my OB and found out that I had a yeast infection. This is my first one in my whole life, and I’m just wondering if it could be a sign of early pregnancy? my periods due in three days, and I had a little spotting this morning, but could it be from my prescription.?Me and my boyfriend haven’t been using protection, we’re just kind of letting nature take it’s course. I just wanted your guys in put, and if you’ve heard anything like this before.!!!
