Okay so I'm nervous

Okay so I'm 11 Dpo and was suppose to get my cycle on the 9th? Nothing then this morning I felt a tightening in Between my Breast and I've been tired even though I've been getting 7-9 hrs of sleep a night. I have been taking metformin for my cycles and since August have gotten some type of cycle ....even with stress and me on anti depression I've still gotten something....my partner and I did have sex on my ovulation days....so could I????? I'm so nervous
