My boyfriend and I have been trying for months to have a little miracle. We almost gave up until I missed my period. And it's been three weeks since I've missed and I've taken a test every other day since my missed period and all the tests were negative! I have a regular period. I never get cramps my breasts never change in size,my nipples never hurt, I didn't get too bloated really, I didn't get headaches, I wouldn't have mood swings, and I wasn't ever moody. But since I've missed my period my boobs are TWO cup sizes bigger. I'm grumpy. I'm emotional. I'm bloated. I have headaches. My boyfriend gets yelled at for touching my nipples. I have cramps here and there, but I don't get sick. Has this happened to anyone else? I'm starting to lose hope and feel like I have a medical problem.
