my husband and I have been ttc for the past 4 years with no luck so far...im currently 3 days late for af and I feel different than I normally do when my period is about to start... I've been feeling bloated for about a week, random cramps, sore boobs, increased back pain, dizziness, feeling uncomfortable and itchy all the time, having troubled falling asleep, and I've been super moody and the smallest things have been making me cry. I'm wondering if I should test and what the best brand to use is.
