Hi, my husband and I have been ttc for about 3 months now. My LMP was April 20th and I should have ovulated between May 1-6. My period was due to start yesterday however, I experienced a light pinkish discharge May 15th then May 16th it became brown and watery, then May 17th the discharge became red but still lighter than usual for a period, now today I had back cramping and bright red discharge with a little tissue (no clots). I'm wondering it is possible to have implantation bleeding first and then have what seems like a period and still be pregnant? I'm having cravings for meat and frozen cups, I feel very hot in the mornings, and I've been feeling very tired and sleepy for about 2 weeks and everything my husband does seems to get on my nerves or hurt my feelings.....Is this a real period????
