Had spotting on 5th 7th and 10th oct. I ovulated on 8th oct. My partner and i BD 7th 8th 9th and 11th of oct. From the 9th of oct ive had cramping aswell as fatigue. The cramping is a pulling sensation in my pelvic area almost like after doing sit ups. I would be very suprised if i did get pregnant we are not "trying" but if it happens we would be more than happy. I know its extremely too early to test as im only 4DPO but what would be a reasonable day to test?
