new and confused

Ashley • Age 35 * Married since 2014 * TTC #1 for 2 years! BFP 11/20/18 ❤️
As I mentioned before I took ovulation test and had nothing *Friday (day 6 of cycle), then bam! Next day *Saturday* at peak. Then after the 2 day smiley face (peak) disappeared, *Tuesday* tested and nothing again! Then next day *today* after that I tested and I have flashing smiley (fertile but not peak).
 I know NOTHING about (my) fertility cycle. Is this normal? Possible? Any advice and input appreciated :) 
Hubby and I had sex Sat night, Sun morning and yesterday night - in case there is some input on that too😉
TIA
