Nervous!!!

So me and my boyfriend has been TTC for about 3 months now and AF is due in 4 days I'm trying not to get my hopes to high, we just want a baby. Recently I've been blaming myself. It just hurts to see the look on my boyfriends face when it comes out negative..recently I've been feeling so dizzy and lightheaded, my breast ache, and ive been eating like crazy Idk if I could be or not. I'm so nervous to take a test. I just hope and pray this month is my month and I am pregnant!❤🙏
