Just need some advice

Sorry for the long post.

So I stopped my birth control in November. We waited 6 months to start trying since we went out of the country on our honeymoon so we started ttc in March. Right before we started ttc my husband was diagnosed with MS. He’s on medication now but still tired so I don’t push for sex more than he wants because I know he’s hurting some days more than others. So we have sex like 4 times during my fertile week. My cycles used to be 28 days while on the pill. After I stoped they went to 32 days. Last month was 38 days and this month I am on day 41 and no AF yet but still BFN. Then to opks... started using them in April and got a positive. Last month and this month I haven’t gotten a positive. So Idk if I am even ovulating. I bought the clearblue advanced digital to try next month then I guess to the doctor if I don’t get a positive opk next month.

I know everything is in Gods timing but I’m getting upset about it since everyone keeps asking when we are going to have a baby and seeing everyone else around me get pregnant ):

Any suggestions on how to figure out if I’m ovulating and if I should BD more or what if I don’t know when I ovulate. I don’t want to keep testing opk because of being stressed but since we don’t BD that much I don’t want to miss my chance.
