Brown Discharge 6 days before period.

My husband and I have been trying to get pregnant. Today I noticed that there was a good amount of brown discharge on my panty liner. My period is expected in 6 days. Normally experience brown discharge a day or two before my period, never 6 days before. Thoughts? I’m reading brown discharge could

Be implantation blood. I can’t take an accurate test yet as it is not 4 days before my period is to come.

My husband and I did it on May 23-25 all of which was my green week and ovulation according to my test strips.

I’m nervous and hoping this is positive as I hope to hear from other women if they’ve ever experienced this and found out if they were pregnant.

Thanks for any information :-)
