Pcos. Please help me.

Hi all! I was diagnosed with pcos around 20-21 years old. I'm now 25. Was with my exhusband for about 5 years and never had a positive pregnancy test result. Been with my now boyfriend for about a year and started taking these pills called 'fertility blend' from gnc about two months ago. My recent period was a day late and lasted only four days. Normally it is seven. My worry is that these pills may not help me and am terrified that I will never be able to have a child of my own. I've changed my diet to help loose weight and hopefully balance out my hormones. If anyone can give me some advice or what your experience was if you took the pills as well, I would so greatly appreciate it. Thank you for reading and for any advice you may give! =))
