Aracely • Mommy of 1 waiting on BBy #2
I haven't had my period since august seen my doctor last month I told him what's going on suggested too have me wait one more week or till the 18th of this month to retest .. No signs of Af my boobs have been hurting like crazy no cramping just backaches here and there  and feeling more tired than ever
