ebf 9 months, no period yet. how long after intercourse should i take pregnancy test?

Anne
Not trying to conceive but also not on any other BC except for LAM and condoms. Condom accident 3 nights ago and afraid of getting pregnant because I'm not sure if I have ovulated yet. Baby is almost 10 months and EBF. Eats solids 1-2 times a day. 
How soon can I take a pregnancy test after intercourse when there's no period yet?
Thanks!
