HELPP

SO... Me and my boyfriend had the sex this morning. Up to this point I'd been good with my pill, but I realised that this time I'd forgotten to bring it. I got home this evening and find I've lost them (no new packs either) so though I haven't taken it today, was I protected doing it this morning? (He didn't do his thing inside me but I know there can be pre stuff). Any help would be fab
