Me And My Gal Had Some Private Time On 2nd

me and my gal had some private time on 2nd of this month,, we had oral sex and then fingered .. and we hugged for some time , naked.... there was no penetration..my hand never came in contact with sperm as i switched hands while fingering, now for the past 4 days she is feeling bloated and constipated. also there were some brown spots after the second day of this happening. she had her last period on 21st may, i am afraid , is there any chances of pregnancy. no other physical difficulties is mentioned by her like backache, nausea , etc
