hi im ttc and last month my first day of my period was 3/22 and i have a 28 day cycle. and on 4/5-4/6 i had light pink spotting around my ovulation days. and then on 4/16-4/18 i had brownish spotting when i wiped and my AF isnt due until 4/19. and now its the 4/21 and still no af and no signs thats its coming. i think it might be implantation spotting i ve read about it in three different pregnancy books and they all say the same thing that you normally get implantation spotting 5 to 10 days after conception and a couple days before you AF comes. so could these mean that im experiencing implantation spotting, and that i might be pregnant. ive had plenty of symptoms like fatigue, frequent urination, headaches, i feel like im on an emotional roller coaster. i dont have the money to buy a test yet. CAN ANYONE PLEASE HELP ME? I NEED SOME ANSWERS
