TWW driving myself crazy

Erin

This was my first cycle ttc and I'm in the TWW now, 7dpo. I've been feeling a tad crampy and boobs feel huge. I tend to get similar symptoms before AF which is still 7 days away so I'm going nuts wondering if it's AF coming or something else...

Anyone else have any other symptoms like this?

I'm also paranoid about excercising. Is it fine to do somewhat intense workouts it should I stick with something less intense?
