Confused

theresa

So me and my husband have been trying to conceive baby #3 and I’m am 7 days late on my period as of today but I have been seeing this really light brown discharge that has been on and off all day since yesterday and I’m really confused i don’t know if it’s my period or what it does not look like my period it’s more watery and has no metallic smell to it like a period does so I’m very confused.
