Yeast infection for 2 months....

When I first got my yeast infection I took 3 day monistat and It didn’t work but I didn’t end up getting another Monistat until 3 weeks later which was a one day monistat.. that also didn’t work. So two weeks ago I went to my primary doctor and they prescribed me two pills (one that week and then one the next week) so I took both and my yeast infection still hasn’t gone away and I really don’t know what to do. My boyfriend wants to do stuff but I don’t know how to tell him without him being like grossed out considering the fact that we’re 14.
