vasectomy and pregnancy question

Savannah
Does anyone's SO's/husband's have a vasectomy? 
Did you wait until the official clear to have unprotected sex, or did you wait until "x" amount of days/months post-surgery to have unprotected sex. 
My husband will be getting cleared in 2 weeks. Last month we had sex and he came inside me for the first time since the surgery, which was almost 3 months post. We didn't plan on it happening, just sort or spur of the moment. We both didn't think much of it with it being so far out from the surgery but now I'm starting to worry. I'm only a couple days late which is normal most times, but do you reccomend I get a test? Or just stick it out a bit longer?
Didn't think I'd ever be asking a pregnancy question after a vasectomy 😂
