7 days late neg clearblue.

So I'm officially a week +1 day late today. No sign of AF, only nausea and slight cramping. (Nothing compared to my regular AF) i took a hcg stick test yesterday got a very faint + (I think posted pic) but I took a clearblue this morning and nothing!?? Anyone else had this? DH and I are trying for #2 7 years after having DS. ​
