2nd round of letrozol and trigger

Aimee • Hello! My dh and I have been married just over 3 years and have been tc for about 2.5. It`s not as easy as we had expected. Just looking for love and support! <3
I'm a nervous wreck. My dh and I did our second round of letrozol with trigger injection this month. I was supposed to test on the 25th. Of course bc it's Christmas I'm going Friday the 23rd for my blood test. I'm so nervous bc this could ruin our holiday...or it could make it the best holiday EVER!!!!!! My breasts are tender and I'm super emotional...I fear it's pms. Glow says my period should start Thursday. Eeeeeeee eeeeeee. I need support ladies
