Am I late or should I just wait??

Andria
I stopped taking my birth control due to some horrible medical issues and i continued to bleed for a week aloe two after bleeding for almost a month on it. Well here comes the 28 and I haven't gotten my period yet. Me and my husband have been using the withdrawal method tho.. Condoms too. But we have only had sex probably 4 times and twice with a condom. Other time he just finished on me. So should I be concerned or should I wait it out since I bled for so long?
