Hi everyone. I am sooo confused!! My last period was on the 1st of feb until the 6th. I have had unprotected sex on the 7th,13th,16th,20th and 27th of feb and on the 21st until the 24th I had a light brown discharge that only a liner was needed. I then had unprotected sex on the 1st and 3rd of March and now my period is a week late. I had a blood test last week and the results were negative and I also have a negative HPT... Does anybody know what could be going on? And when I would have ovulated? Could that brown discharge been a early period? I'm so confused:S the doctor said I have to go back in two weeks if I haven't got my period!
