I just found out I'm pregnant!

I just found out this morning that I'm pregnant!! I tested with First Response and used my first morning's urine. I got a BFP! My symptoms for the last two weeks have been: No AF, gas, heartburn, increased clear cervical mucous, light cramps and bloated feeling, soar boobs, lightly constipated, increased sense of smell, vivid dream that i gave birth, irritable on and off, and stronger urine smell. I think I am around 16DPO today. I went to the doctor this morning for a blood test to confirm and I find out tomorrow. I even showed my doctor my First Response test and she confirmed it for me. I can't stop looking at it either! I'm in shock. I think i'm just past 4 weeks pregnant. I went off BC in late October, and hubby and I were safe for three months, but this past month our rythem method didn't work that well. But we are excited! I told my best friend and my brother, but that is it. I am going to wait until I am further along to announce the baby news! Good luck to all and if anyone has any questions about pregnancy symptoms feel free to ask me. I hope all of you are getting the answer you're hoping for!
