Pregnant?

Cay

I had unprotected sex Jan 3. The same day my period ended. He pulled out way before he finished. I did not take plan B. I currently think I either have Bacterial vaginosis or a yeast infection. I have no other symptoms of pregnancy other than maybe being tired more but I think that could also be because of the weather change and it being gloomy and not eating good/ kinda going to bed late. What do y'all think?
