First time trying ovulation strips, any info will be very appreciated!

This is my first month trying Wondfo ovulation strips after having an ectopic pregnancy in November and I’ve been getting faint lines but nothing as dark as the control line..I took a test today and I’m hoping this is a positive?? It’s the darkest I’ve gotten so far.💜 I have a 33-34 day cycle and this is 17 days in.
