hard to get pregnant with our any reason?

Rose
After unsuccessful fresh transfer with <a href="https://glowing.com/glow-fertility-program">ivf</a>, this month we had our frozen transfer last Monday, and my pregnancy test will be on Thursday. But I always have my period symptoms before one week of my period and it's making me more frustrated. I don't know what is wrong with me why I can't get pregnant? Why I always get my period? My reports are normal even doctors said me she will be surprised if I can't be pregnant. What should I do? I know before I go for my pregnancy test, I will get my period. Please help me ladies, is there any solution for my problem? Can it be any problem in implnatation? Does anyone have similar experience?
