I have been feeling odd for the past three months. First I started gettikng acne that wouldn't go away after my period and then my nails began to get stronger and grow faster. This is something I really picked up on because in my last 2 pregnancy, my nails have been great and then back to peeling and soft afterwards. Now for the last 2 days it feels as though i have done 100 sit ups, but i haven't even done something to strain my stomach. My period should be coming in the next week or so, but it is never on time. Last month is was 2 weeks early. Does anyone know about what I am feeling??
