Shocked at my BFP

...So we did it cycle day 9, 18 and 19. Normally my cycle is 29 days so these days are not even close to my predicted ovulation times. I had a miscarriage in July and had very early pregnancy symptoms to go off. I have had zero symptoms this last 2 week wait. Except my period was two days late. I did not think I was pregnant because it feels like my period should start. I just did a dollar store test and can't believe my eyes!!!! My rainbow baby. So ladies keep trying on your not predicated ovulation days, YOU NEVER KNOW!!!
