7 days late

I'm 7 days late with no sign of af showing just took a test and it's negative.. me and my SO BD the 5th and 7th of this month so I don't know if it's still too early for it to show... my symptoms include tender nipples with bump round them, lower back pains, a lot of clear cm till the point it feel I've wet myself 🙈, tired more them usual also peeing more then usual and experiences stomach cramps but very mild and not everyday, also my n my SO BD again last night n when I cleaned up I had a little bit of brownish spotting colour but nothing since..

Any advise please?

Has anyone experience this after 7 days late with negative test?

I don't know what to think anymore 😧
