I am usually very regular, normal 28 day cycle. My period started on Augyst 30 and ended about the September 5. I had sex two days after period ended and the condom broke. Took Plan B about 45 hours afterwards. Three days later I started bleeding brownish blood, which continuted for about 4-5 days. Bleeding ended about September 8th about I am not sure if this was a period or what? It is now October 8th and am not sure if I am due for a period any day now or if I am actually about a week late. Had sore breasts last week, which normally doesn't happen but no soreness this week. Wondering if I should be patient and wait a few days to see if period comes or if I should take a test ASAP-though I want to avoid a false negative and not sure if its too early to test. Thanks in advance!
