My periods are always regular and i always have either a 29 /30day cycle however this is the first month of ttc and now i have started bleeding on cycle day 27 , the bleeding is not light but milder than usual but i do have cramping that feels like period cramps , i was convinced i was pregnant due to experiencing many symptoms especially tender boobs but now im really confused could this be implantation although seems too much blood for that, i would assume period but ive never had a period start this early before ? Any advice is gratefully received
