Advice please 5dpo?

If I had my period on the 25th day of cycle instead of the last two months being 27th when should I test this month period is apparently due the 1st , I believe I ovulated on the 11-12th as I had my solid smiley on the 11th, have white cm in cervix , cervix is also soft and feels closed I’d say. Had little back ache yesterday and day before in evening very dull but felt it, and past two days little twinges on and off on ride side of pelvis then would switch to left or vice versa ..
