Destiny • 1 little one and 1 cooking
Lol im new at this and i am very curious about everything because i just want to know , but my most fertile day was the 7th(33%) , we had sex on the 6th but all my doctors saying i concieved on the 8th(22%). Does like the egg latch on before you actually concieve or what? Did i conceive on the 7th or 8th, im currently 8weeks +1day
