Looking for advise

So I had a miscarriage in February and stopped bleeding 3rd feb, hid my period then 4th. Arch as you can see from miscarriage to then it was 36 days ..I then got my peak in the 18th march and you can see when we had sex, I am now 2nd April, period was expected as you can see yesterday ..frer coming back negative/ vvvfl or indent (I think I’m seeing what I want to see) ..I still haven’t got my period ..done with testing ..when should I expect my period again ..I’ve never had a cycle longer than 32 days and usually I’m regular at around 29 days ..pics attached..when should I consider I may be pregnant and test again
