According to glow my period should have came on 12/27, today is the 30th and none of my usual signs of period coming, no cramping, no spotting, no period. The only sign of my period coming are a a few big pimples on my face. I took a clear blue pregnancy test this morning and gave me a Big Fat Negative😢. Could I be pregnant and be too early to detect hcg?? My periods are always off by a couple of days every month, but now that we have been trying to conceive for 3 months now and tracking my cycles I don't know what to think..we are trying to conceive baby #1. I'm 31 yrs old and my hubs is 33.  We have been married for 5 yrs. I'm on cycle day 39 right now, the last 2 cycles had not been this long more like 32 and 35.. I feel so sad and depressed, what if my cycles are always different therefore this app cannot really help me track my most fertile days. What do you ladies think?
