Casandra
Woke up this morning to feeling sick to my stomach... Also my nipples are mega sore and hurting, I've felt like I've had to puck all day, and all i wanna do is sleep. I know i am due to puck any second now i just know it.... I've also had a really bad headache all day, I'm feeling dizzy since about 7:00pm and every time i eat something i feel even worse.... But i noticed i believe yesterday that my vagina or like up there in it it felt like "pressure"i guess you can say. Idk what to do I'm not suppose to start til i believe this Friday.
