What are some over-the-counter medicne or other ways to get pregnant easily.?

Patience. There's no otc medication or supplement that is shown to increase fertility. Many couples with normal fertility have to try consistently through several menstrual cycles before conception. Only after a full year of consistent unprotected sex do we consider fertility impaired; at that point, a reproductive health specialist, usually an ob/gyn, can help with testing and options.
Ovulation Kit. I think an ovulation predictor kit; it will let know know the best time to have sex. Hope this works for you.
