Help! Anyone else had this happen?

I had 7 days of flashing smiley face on clearblue advanced ovulation and on the 8th day( cycle day 16/17) I got a peak reading. I decided to take another one Monday after the solid smiley had went away and I ended up getting a "high" reading so I decided to take another one Tuesday and it was back to the "low" reading , took another yesterday it was back to "high" reading and today too. I'm having a ton of discharge and that's not normal for me to have after ovulation. Has anyone had ovulation test do like this? With our first baby I took the clearblue advanced too and the month we got pregnant I kept testing up until a few days before we found out and I kept getting "high" readings I just thought I had missed our peak reading but turned out I was pregnant.
