I'd like to join your thread! I'm kind of in the same boat. I had a hormonal imbalance from 20-21 y.o. right after I ended the nuva ring but, since then, I've been regular. I'm 25 & every 31 (sometimes 33) days. I'm now on CD40. I use an app that predicts my period every month with scary accuracy! I used to chart but I was becoming too obsessed with temps so I stopped. Now i usually wait until my boobies become sore and then chart my symptoms. This month I kept thinking "hmmm" is my period coming soon but, again, I try not to look until I feel the symptoms. I started cramping on Thursday so I thought "period time" and when I opened the app I realized I was late! Now taking my avg. cycle length of 32 days, I'm about 7 days late. I took a cheap pg test yesterday morning and it was negative. Could I have tested too early? I'm afraid to test again because I dont want to see that bfn. What do you guys think? Baby dust to us all!
