Please consult gynaecologist near you with all the examinations you have had till now along with all your treatment history. There are many lines of treatment for infertility and taking some medicines unsupervised or for long time can affect ovarian reserve, further making treatment difficult. Ivf is generally done when there are no treatment options left for pregnancy and is nothing to be scared about with the amount of progress medicine has done. Go to a good infertility clinic.
