Ovulation test (I am new to this app)

I've been doing ovulation tests for about 6-8 months on an off and they are always coming up clearly negative and I don't have periods. I came off injection just over a year ago. I also had a laparoscopy on the 20th of last month that confirmed that both ovaries and womb uterus etc are fully working and there was a slight blockage in 1 tube which is now gone. I have done an ovulation test today and there is a very dark line and a faint 1. Is this a negative or a positive???? Please help me and any advice would be greatly received as I am feeling it's never going to happen.

I also have had 2 children healthy pregnancies which were one was conceived on the pill and one just after coming off pill from a previous relationship.
