Sorry I know this must get asked all the time but I'm just a tad confused ...
First month ttc and being a bit of an eager beaver 
Period started on the 15th Aug, Ovulated (according to tests + Ewcm) on the 29th and I usually have a 28 day cycle.
Should I test around the 12th September?
I'm due to be having an ultrasound on the 9th September, but I think (if I'm lucky enough to be pregnant) it would be too soon for them to tell!!!
Thanks mamas x
