My period was due October 10th, I didn't get my period until the 14th but the odd thing was it was 5 days long as usual but it was super light. My periods are usually heavy to wear mi changing about every 2 to 3 hours. it wouldnt even fill up a pad in that time. The color was bright red some dark red at times and i passed a clot about the size of a penny. My breast are still super swollen, more back pain (upper and lower) Could this be pregnancy? I have multiples that run thur my whole family, (moms and dads) could it be a multiple pregnancy? I took a pregnancy the day i missed my period but i feel tht is was to early. Could this bleeding have been implantation bleeding. Ive also never cramped after my period. ive had mild cramping as well after the bleeding stopped.
