Trying to conceive.. help

Me and my partner have been TTC for 5 months now (yes I know it can take up to a year to conceive) 
I use to be able to tell when I was ovulating until about 8 months ago. 
I have been using ovulation test , tracking my temp and using elevit. 
Last cycle my period was 5 days late..
I was meant to be ovulating now but because I was late I'm not sure. Have been taking ovulation test for the last 6 days and was having unclear results , so I tested again with another brand and got a low line. 
I've been cramping really bad and having left and right cervical pain.. 
not sure if I could be ovulating now or not ? 
Would love someone to talk to about this 😬
