catch the egg or not?

hi ladies,

I'm pretty new to ttc. went off bc after last af at end of June and had my withdrawal bleed 2&3 July. have not had my period yet. had cramping 28&29 July and I'm pretty certain ewcm on the 30th plus a positive opk (showed up in seconds). so dh and I bd on the 30th and 3 Aug, was wondering whether we caught the egg or not? also when is at likely to show her face?

thanks for your guidance
