what's going on?

Tasha • Married to my high school sweetheart 💖 With two beautiful babies! 💖💙 Pregnant w/ #3 🥰
I'm 34 weeks, 35 weeks Friday.. today I was at a reunion, with my boyfriend & family & what not ya know... I have felt so sick ever since I got home.. Like I just want to pass out, cause I'm so dizzy. I just went to the bathroom & I could hardly walk, it kind of hurt. I just have this feeling that I am going to be giving birth sometime soon, maybe within 1 to 3 weeks. Or sooner even. I just feel it coming, she's a big baby as it is. Anyone else feel this way? Am I going crazy or what? Should I get my cervix checked when my appointment is on Wednesday...?
