Prayers

So I tested one time and it came back invailed because I tested on ovulation day. I used pre seed this cycle for the first time. what do you guys think? Could I be pregnant? So far my symptoms are nausea, I threw up a few times, really bad back pain ( which I thought could be a possibly a UTI but I got tested and it came back negative and I drink enough fluids as well) I'm very moody, a few weird food cravings ( which I normally do sometimes anyways) and a little more exhausted then normal *hint I had a missacarriage in September 2017*
