What have i done? What do i do? Help!

I don't ovulate according to blood tests so thought i would try soy isoflavones. Had some bleeding after sex on the 29th which then turned into spotting on 30/31st, so took soy day 4-7 (today is day 8 so should take last soy today) but after sex yesterday i had some pink cm, put it down to being rough lol. Then did some yoga last night (crab position.. felt a few shooting pangs around ovaries) then had a small 'gush' of red blood (day 7?!) Today it is mainly pink and a little bit of brown/old stuff i guess?

So i'm confused as to whether last night was cd1 or was it a random cd7 bleed from strenuous exercise? Here is the thing.. i just did an opk and yes it is negative but there is progression from yestersdays negative.. it's starting to get dark(er) ... what the heck? Did soy mess me up? How can i dtd if i'm still bleeding? What do i do? Has anyone been in the same situation??? Xt
