I have two period tracking/<a href="https://play.google.com/store/apps/details?id=com.glow.android.nurture">pregnancy apps</a>. One says my period was to start on the 10th, another says my period doesn't start until the 14th. I don't know how long my cycles are. I've also been having strange cramps and sore nipples (soreness in my boobs as a PMS symptom has never happened). You ladies understand how hard the 2WW can be, if I'm pregnant I would want to know ASAP!
