So upset

Ladies I'm so annoyed and frustrated. I'm currently 18 days late for my period. Multiple pregnancy tests all came up negative. So being the person I am I just assumed i must have skipped a period so i began testing for ovulation to see where i may fall. So these are my strip progression for the last few days. The darkest one is from today. I'm just so frustrated and confused because on 01/02 I had a positive LH strips. Following day I had cramping on one side and fertile cm. What do you guys think? Did I just skip a month?
