Update- I'm on my 7th day of ewcm! Is this normal? It's not all day, it's in batches of one, two or three throughout the day.

I'm now cd 17 and I've had tightness in my pelvic area every day since cd 15. I thought I had actually ovulated on that day (cd 15) because I was headachy, sluggish and felt a bit sick actually, my sides felt achy and uncomfortable. But more ewcm today so DH and I dtd just in case and my pelvic/uterine area - centre front and across - felt so tight and heavy dtd was actually a bit uncomfortable... Weird hey?! Is three days of cramping normal? You would think I'd know since it took 18 months of TCC DD1 but back then I wasn't paying that much attention, just flying by the seat of my pants!
