Slow period start or implantation bleeding

[Kate91]

Hi there I have two kids already youngest about to turn one. I've always had very irregular periods. Came of implant after six years and fell pregnant immediately but had a miscarriage then caught on right away again with my youngest. Im now having thick discharge flicking between streaked with blood or completely tinged. I know with out taking a test there's no real way to know but do you guys think this could just be a slow start to period as they've never been regular or consistent in how they are or do you think this might be implantation bleeding. Can't get a test till next week as don't get paid till then.

I think there's no point in second guessing yourself. I'd wait till next week to get a test... in general you should test at least 3 weeks after having unprotected sex
