Terrified to be Excited.

Theresa
Husband and I have been trying for #3 since I got home from deployment in November. I fell pregnant in January, but miscarried in February at around 8 weeks. I was completely devestated. We picked up the pieces and kept trying. I fell pregnant again in June, and when I went to the ER after a bit of blood from sex scared me, instead of seeing an 8 week gestation fetus, I saw a gestational sac with no fetal pole, and knew that the miscarriage was imminent. Once the bleeding stopped, around the 10th of July, my levels went back to negatives by the next week. Husband and I keep on trying. Having no idea when to expect AF, I've been testing. And then this morning I got this. Do I dare let myself get excited?
