Hi, sorry this is long! I have been off the pill/TTC since August. Before going on the pill my periods were irregular but regularly irregular (Between 35-42 days). Since coming off the pill they have been harder to predict. Here are the length of my first 4 cycles since coming off the pill: 1) 36 days - 2) 35 days - 3) 50 days 4) 43 days. Since then is when I am unsure what my cycle length is. 28 days ago, on my 58th day of my 5th cycle, I got brown discharge one evening so I though AF was due. Following day I had much heavier brown discharge, not enough for a whole tampon, but too much and too dark to just be regular discharge. The following day practically nothing. I asked on here and people said it was likely a very light period. So I put it on to my tracker as my period. I am now cycle day 28 and have just unexpectedly started my period. It is very unusual for me to have such a short cycle, even though it is regular for most. So my question is, was the discharge not AF and I have had a very long 84 day cycle or was it right to log the 5th cycle as AF and I have just had my first short/regular cycle? Want to put it in to the tracker correctly or my predictions are going to go off....
