there is always a risk associated with condom failure,however i would,nt be worried about the oral sex,that wasn,t a risk. to answer your question,testing at three months will give you a conclusive result.do you need to test again at 3months i say yes.all the best.
Yes ! Your 10 days tests are not conclusive. You need to get yourself tested after 6-7 weeks of exposure and a follow up test after another 6 weeks.
