My period was 2 days late. I then had brownish, occasionally tinged with red spotting for 2 days. I then had my period for 2 days; 1 days was like a normal period and the other day was light. I only needed 2 use 3 tampons over the 2 days, over these past 6 days I have only had 2 use panty liners those 2 days I used tampons. The flow on those 2 days was a dark, dark red or brown. I have now had brownish spotting again for 2 days. 3 months ago I used the morning after pill and it changed when I had my period, however, I did have a normal 3 to 4 day period the month after I used the morning after pill. I am not on any form of bc, we use condoms. I have been down in the dumps for about 10 days but I dont know if it is because of hormonal issues or work being stressful or because the relationship I was in is going down the tubes. I have also had back pain and occasional twinges in my lower abodomen but not really cramps. Any ideas? %-)
