Irregular and Confused

So I went to the doctor for an irregular period since my husband and I are TTC. I was regular from September (when I got off BC) to December (last day of that period was January 1). I didn’t have another period until April 6th. Between that time I went to the doctor and had bloodwork done.. everything came back normal.

My question is... are any of what is pictured below (besides the LH hormone) a test to see if I am ovulating? If my tests came back normal, is it wrong to assume that yes...I am/can be ovulating like a person with a normal cycle??
