Advice

Hey guys! Okay, long post ahead, so sorry in advance. I’m 21, have been married for 2 years, and we are ttc our first baby. We’ve been trying for almost just as long as we’ve been married with absolutely no luck. I have been checked in and out (HSG test, blood tests, ovulation tests), my husband has been checked as well. I had my period start on the 16th and end the 21st, i had a predicted fertile window from the 23rd to the 2nd. We BD 23-26th, and 28-2nd. I’m currently 8 days away from AF and I’m wondering a few things. When is the best time to test, and is there anything that I’m not doing right? It just seems that I’ve tried literally about everything to track, and nothing. What gives 😞 words of encouragement would be so greatly appreciated.
