Going into 5th Cycle of Clomid.... Any advice based on my charts or previous Clomid experiences???

Here are my 2 charts. I'm pretty sure AF is coming by the way they look. I'm going into my 5th cycle of clomid. Last cycle I added preseed. This cycle I'm gonna try preseed and Fertility CM since clomid has taken all the moisture. Any thoughts/advice? I dont want to give up but I'm getting close. We've been TTC for 19 months. All.... and I do mean ALL of my close friends have conceived... Even the one who's tubes were tied. I'm happy for them and at the same time trying to figure out what I'm doing wrong.
