So confused!!

Reva • Mother of four children in a blended family, trying for #5. I`m an RN trying to balance family and career.
I took a home ovulation test yest and it was faint. I took one today and the line wasnt there. I'm supposed to ovulate today but my cervical mucous hasn't changed. My cervix is lower today though. Anyone go through anything like this? Any words of advice?
