Trigger shot time!!

So back in June I had my follicles checked. They were only like half a centimeter. They want them to be 18-20mm. So my Dr put me on my first round of Clomid. I had my first round of 50mg clomid and yesterday was my cycle day 17 & I went back in for them to check my follies again. There were no mature follies on my left ovary but when she checked my right ovary she measured a mature dominant follicle at 24mm!! I cried like a baby! So today I will be receiving my trigger shot by FedEx & will take it this evening. Any of my fellow glow friends taken the trigger shot? Any side effects? What was your success story? Also, how long after you take the trigger shot can you take a pregnancy test? :) ❤️🍼
