Well this cycle was a very short cycle I really don't know what to think about it. I normally have a 4 or 5 day cycle but this was only like 2 1/2 days. It started on Oct 2 it was in between heavy and medium flow, on Oct 3 it was between medium and light. On Oct 4th I woke up kinda bleeding but by noon it had all stopped. Since this was a short cycle I am wondering when I should start doing my OPK's. I am going to by like 2 or 3 boxes this time so I can test everyday. There are only like 7 or 8 in the box.
