Can I still be pregnant?


So my period is due in 4/5 days. My apps say I ovulated 9-10 days ago. I haven’t been tracking my ovulation with test strips because Thai is our 4th month of trying so I wanted a break and just relax to see if it will happen. I tested this morning and got a negative. Is there still a chance I could be pregnant? I have sore breasts which are more tender than normal before my period. I had some light cramps at 7 dpo. And back pain the last few days.
