I took a First Response HPT today at 18DPO and got . It was light but it was there. My LMP was July 13 and I Ovulated on July 29. I have "felt" pregnant since before my missed period but since we have been TTC # 1 for just over a year, I wasn't sure. I received a BFN on 12 DPO and was crushed, but AF still didn't come and symptoms kept getting stronger. My boobs are killing me, I've felt sick the last 3 mornings and off and on throughout the day. Plus 100 0ther symptoms, including 18 days of high temps. I think it is still sinking in for me, that this is real! Due date calculators tell me I am due on April 19th.
