today my boyfriend came over to my place and we had oral sex. I gave him a blowjob and he fingered me and inserted his finger in my vagina. Later we realised that he may have had precum on his fingers because I could taste something salty during the blowjob but it wasn't cum and he touched his penis a couple of times. He says as far as he can remember his hands were dry every time he touched my vagina or inserted his finger in. The last time he ejaculated was last night after which he peed twice. the first day of my last period was 4th December and this should be one of my fertile(ovulation) days!! Could I be pregnant??
