I've been TTC since November 2014. I learned in February that I have thyroid issues that will mess up my menstral cycle. So naturally I was upset. I didn't have a period December or January. I had one in February, and I missed March. I took a test 3 days after my missed period, and it was negative. Then my boobs started hurting for two straight weeks and I finally decided to take another one and it came out positive. I went to my general doctor and they confirmed it as well. I just wanted to share this for people who feel like they want to give up. Just when you're at the giving up point, a miracle can happen. My doctor said I should be about 6.5 weeks. :)
