So here's the scenario. May last period is Nov 11 it lasted up to 5-7 days. Then me and my husband had unprotected sex on the 20th but i think it's 21st cause we did it i think it's already midnight. Then after 3-4 days i had spotting on the 1st day it was like blood tinged mucus, then the next day itbwas brownish discharge. I had spotting for 4 days and on the fourth day i take a HPT and it came out negative. I have a 33-35 days cycle. And my next period is due on Dec. 16th. So from the day i had spotting i still have 22 days till my next period. I need HELP here!
