My cycle has been 31 days for past 4 cycles.

BUT according to my temp I ovulated at 31 days. Then yesterday at 7DPO I got a light period. Started spots in morning yesterday then a tissue in over night. Todays Its very light (for me) and has some stretchy brown clots.

My temp did go down today but not much so still way above coverline.

I did a test but negative.

Tomorrow I am going to get my 3 day blood work.

So, if it stops will they still be able to do the 3 day test? Its a long way to go so dont want to waste a trip and day off work.
