I had unprotected sex on the 1st of January with my partner and I was due on my period on the 19th I didn't come on buy on the 20th I went to the toilet and wiped noticing a brown discharge on the tp. It lasted for 3 days and then I began to bleed slightly heavier for 5 days I took a pregnancy test 2 days before period was due and it was negative. Any help? Xx please x

Can't do pregnancy test that early, you have to be 2 weeks LATE to test, so first test was useless. You can wait and test at 2 week late and see, if not, you wait for the next period and see if it comes normal. If it does not come normal, off to the doctor for an exam
