tmi question discharge????

so I'm not really sure of all the abbreviations so I'm just gonna type it out but anyways so I ovulated the 3-9th my highest days ended up being the 7th n 8th my husband and I had sex every day of my ovulation well I'm not supposed to have my period till the 22-23rd and last night I started having the weirdest discharge it was a light brown n looked like it had a few seeds (darker brown) in it n it was just a tiny amount when I wiped but it's happened 3x so far this has never happened so I have no idea what it could be n was wondering has this happened to anyone ? does anyone know what it is or could be? I can't try to post picture later if it happens again I'm just confused n don't want to get excited if it's nothing or something bad lol but my period cycle is pretty regular so idk if it's just getting ready to start or what any info is appreciated lol thank you!!!!
