Period like cramping and slight nausea 6 days before AF due?

? Kristina ? • ? I`m 23 & live in England ? TTC #1 ✨ Had a chemical pregnancy on 24/09/2014 ?
I've been feeling slight nausea lately but today I've been feeling icky all day and now I have period like pains across my abdomen. I've been feeling very down today and lacking energy. Anyone else experienced something like this? Thanks
