Bailey • I loved you from the moment i knew you were there, and I will love you till the day I die ❤ 🌈
My boobs have been so sensitive and my nipples have been Itchy! I've been having occasional nausea and hot flashes, and lower back pain. I've been a little more crampy than I normally am with af. I'm just not sure if it is my body getting ready to start or pregnancy symptoms. I'm supposed to start in about a week, so I just don't know if that's to early to test.
