could i still be pregnant???

butterfly

i recently came off the pill as i decided to give my body a break after having my little one (5 months old) and we had sex for literally 30 seconds and he didn’t finish or anything. every other time we have used a condom. It is 1 week until my period is due and i’ve been so tired for the past couple of days i’m SO crampy and i’ve got such bad back ache and i’ve been suffering with headaches. Am i just being paranoid or has anyone else has these symptoms?

thanks in advance x
