Help??

Right can anybody help? During my fertile week in July I had bad paint on right side on the 25th witch I'm assuming was ovulation pain, I didn't take an ovulation test tho so I don't know for sure, so I really don't know how manus dpo I am, I did a test yesterday and it was negative but I am experiencing really sore breasts to the point I can't lie on my front and I have felt sick for the past 2 days, I also have a change in bowels actions too, when should I test? Only came off the pill at the start of June :/
