Could i be pregnant ???

My period is usually never late. Especially never THIS LATE. All pregnancy test came out negative. I even went to a pregnancy facility and i have this type of watery/creamy discharge since ovulation. I felt pregnant the week of thanksgiving but only in the mornings. Only getting symptom( extreme fatigue, nausea, metallic taste in mouth, burping a lot, high BPT) in the morning and feeling better in the evening. Now it’s not as bad in the morning and i mostly feel fine. I know Yal aren’t doctors but maybe someone has some suggestions 😖
