Hey I came off of nuva ring BC in December. First day of period 1-9. I have been doing the OPK since the end of my period and have not missed a day. Still no smiley face-including this morning when I did it. I test at the same time everyday as the box recommends. I noticed a light pink gel like discharge today. Could this be ovulation? Even though the OPK didn't detect anything?? I don't remember ever having this before, but I have been on BC for about 8 years.
