I am using the <a href="https://play.google.com/store/apps/details?id=com.glow.android">glow app</a> to track my cycle. It is supposedly due on 2/4/15. However; everytime I start my cycle.. There are times where I hardly get any symptoms. My question is; is that normal. I am 34; and have been on fertility meds for a year off/on.  I assume my cycle is out of whack bc of all the meds I have been on. Also; my cycle varies from 2-5 days. Normal?! I don't know anymore...lol !!!
