26 days late

Ta

My period is 26 days late. Is this normal? The only time my period has ever been late is when I'm pregnant (both miscarriages). I had a miscarriage in February this year and my period has been normal after that. I don't feel any different. Last week I had cramps and thought my period was coming but still nothing. Tests are negative but after like 10minutes a faint line appears (I know it's invalid after 10mins). My boobs are super senstive today though. I'm not sure whats happening. Should I go to my gynae?Or just wait?Am i overreacting ? 26 days is a long time lol
