my husband and  i started trying for a baby in Jan 2012.  I had my period 2 weeks ago on 1/17 which ended on the 22nd. on my phone app it says i should be ovulating the week of 23 - 28.  So on Feb 1st are started getting cramps and light bleeding. the next day I checked to see how much blood was there and there was hardly any. very little brownish color. Im wondering if this was Implantation bleeding? ovulation bleeding ? my next menstrual cycle isnt till the 14th.  Please help  .
