Fertility Med

I have struggled to get pregnant for going on 4 years in August. I got serious over a year ago and began tracking my ovulation with opk'S and a bbt thermometer. No luck. I finally took the big step and went to see a specialist just a few months ago. They literally have found nothing wrong with my SO and I after running so many tests. The doctor started me on Fertility Meds this past cycle and I am praying so hard this is the key to finally becoming a family. I've never wanted anything more than this and my heart aches so much every single month that we are let down. Aunt Flo isnt due for another week and my boobs are beyond sore. What are some common early symptoms you have noticed?
