HELP!!

Okay so I've come off my pill because it was causing me to be depressed so the only contraception me and my boyfriend use for sex is condoms... Except the other week I wanked him off and when he came he cleaned up and put his dick away then he returned the favour and fingered me ( we didn't do it at same time Coz we're normally lying down and it she's my arm so I sit up while he lies down) except I think he may of had some cum on his hand/fingers though because for just over a week I've felt pregnant :/ like cravings, moods, sleepiness, EXTREMELY sore and tender boobs! etc :/ this was just before my last period which was 5-7th November
