Hello everyone

So my husband and I have been trying and last month we has sex on all my ovulation days I was suppose to get my period on the 10th of this month and I still haven't gotten it my breast are tender and nipples are sore but that usually happens with my period I keep thinking I'm going to get it but before I even missed my period I had a vivid dream I was pregnant also I've never been this late I heard you can use a ovulation test because it can detect the same hormones as a pregnancy test I took one and there were two lines one was more faint though it doesn't make sense if I were to get my period why would the test come back postive can I be pregnant ?
