Pregnancy after miscarriages

Talitha
After 4 years of trying, and 3 miscarriages, we are pregnant again. I am currently 6w2d and am trying not to worry. I've had nothing but good signs (sore breasts, acid reflux, fatigue, and short bouts of nausea). But because of our past history, I'm afraid to get too excited. All of the past 3 losses were dues to my body's lack of progesterone. This time I'm taking progesterone and my levels are GREAT. I go in tomorrow for an ultrasound due to my history. Any other mamas out there who have lost littles before?
