Help! Need Advice ..

Before I begin... please no bashing on this post. My husband and I have been married almost 4 years. We have a beautiful 3 y.o who was recently diagnosed with Autism. This journey has been so rough on my husband and I because of the constant therapies, tantrums, communication delay etc. My husband has decided that he does not want another child because he’s afraid our next child could have autism or worse . Even if the child develops perfectly he fears we won’t be able to equally devote our time to both children as we have hectic schedules. I want another child just maybe not right now (we’re in a pandemic).

Anyways.... I’m on the patch and my last cycle was irregular so I decided to skip a few weeks until my period comes back so I can be on track. I made this known to my husband SEVERAL times before we’ve had sex. He said “ok”. I could possibly be pregnant but im too anxious to take a test just yet. I want to prepare my husband before I take the test so he won’t be surprised if it is positive. This may be a silly question but how do I have this conversation with him without the “I told you so demeanor” ??

OR should I wait until I take the test to talk to him?
