So here's the thing. I had my period on July 8 and it ended on July 12. I had protected sex on July 16, yes, it was with condom, it did not break, it has no tears. As i got home, I took the ecp already probably 9 hours after the incident. 7 days later, bleeding came. It lasted for four days, bright red, as heavy as my normal period. And right now, august 28, I still do not have my period. Someone told me that after a breakthrough bleed, you must have your period next month not being late more than 5 days. It's now 5 days late and I still do not have my period. I only have too much white discharge which turns to yellow, back pain, tender breast and about 2 nights ago, I noticed a small brown spot on my undie. Could I be pregnant? Pls answer me :(((
