Curious

Okay so my periods have always been abnormal I had a D&C back in 2015 to help with that and I don't think it helped at all so I had my last period in Dec. but it came on in the Nov the 27 and stayed on til the 14th and I haven't seen one yet and yes I have been TTC and I had sex on supposedly been the day that I started ovulating I haven't thought about take a test bc I don't want to be disappointed so any suggestions will help thanks a lot
