so i have a simi period may5-7th . my period was a week in a half long due to no birth control after my daughter in october . so may 5th was my period and it wasnt even enough to fill a pad nor tampon ,  and the day my ovulation took place i spotted only when i whipped for a hot second . when should i test?
