My cycle has been a little off the last few months. It used to be 28 days every month, not a day early and not a day late but the last 6 months or so it will come anywhere from 24-28 days. So my 28 day mark is next Tuesday, March 25. Well 2 days ago, when I wiped I had brown blood and it was ONLY when i wiped. It lasted about 2-3 wipes and then it was GONE. Since yesterday, I have had the worse cramps and backaches. Yesterday i had some white discharge, not a lot just a little. First, does that sound like IB? Could it have been a pre-preiod and I should still expect to get my period? If it was IB when could I test? Thanks,
