Itching and discharge. For infection?

Hi, I have been experiencing itching in the opening of my vagina from a couple of months. It's not constantly itching but it is uncomfortable. I also have noticed that my discharge has become more and is thick white with no odor. Sometimes when I insert my finger I notice broken cottage cheese like discharge but no odor at all. Everyday morning when I wake up from bed, there will be too much discharge in my panties. I last had sex in the month of October 2021, I use Menstrual cup during periods and my last period was on 26th January. I get periods regularly as well. Last time I had sex, we had used a flavoured lube for the first time. I had never used any kind of lube in the past. Could this be a reason for infection? Please suggest a medicine for this. I am not able to visit gynaec due to busy schedule, hence seeking help here. Please consider.
