I'm going to get blood work next week because 12 days late on my very normal period is way crazy. Anyway, in the meantime, what should I be doing in case I'm pregnant? I'm not drinking, i don't smoke, im not eating sushi or soft cheeses and I cut back on my coffee intake. Oh and I've been taking a prenatal for a while now just in case. Anything else I should start doing?
