When should I test?

Well, I'm embarrassed. Hubbie and I had an oopsie last Saturday night. 😅 I stopped taking birth control a few months ago and we've been using condoms but didn't use one this time. I'm breastfeeding and haven't gotten my period yet. We're totally okay about the possibility of being pregnant, almost a little excited infact. Idk when I'm ovulating or if I even am because I've got no AF calendar lol. Anyway, when should I test? It's literally my first time ever having unprotected sex without actively trying to get pregnant...so I've never done this before. 😂
