Hi i'm 26, weight 127, height 5'4'', i'm irregular on my period, on july my period lasted about 10 days and this month it started on August 2nd and ended august 4th and i had sex on aug 10th without protection. I noticed today (aug 13th) was my peak day with billings method, and i was wondering if i had any chances of getting pregnant with this information. Something else, my husband had unilateral cryptorchidism during childhood. could i get pregnant??
