HELP!!

Hannah
Okay, I really think I'm pregnant.... but it's not time for my period yet. So I was wondering what y'alls opinions were! My last period was over 2 weeks ago and I just finished ovulating I'm having ALOT of discharge like it's bad enough that everytime discharge comes out I have to change my panties. And I started having really sharp pains in my boobs a couple nights ago. And I was having period like cramps 3 nights ago like implantation cramps. And I've been having headaches and heart burn really bad just about everynight.... if I am pregnant this would make my 4th child. I just can't remember what signs I had before I took a test with my 3 oldest! We are hoping that we are pregnant bc we are trying!!
