According to Glow & Pink pad I ovulated April 4-10 & I BD from the 6-11. I'm only about 8DPO, but I feel sick a lot. It's not like I have to actually puke, but to where I have the feeling that I do . My boobs are abnormally tender as well as my nipples. I also have back and neck pain a lot to where I can't get comfy. Once in awhile ill get a headache for about an hour and it'll disappear. My CM makes it always feel really wet down there & it's clear but sticky-ish. Could it possibly be an early sign?
