It started when I noticed I was sleeping alot on my vacation for 2 weeks. Then I noticed that my favorite foods were tasting different. So I took a test. It showed 5 dots on the positive. 3 days later I started my period but it only lasted for 3 days and not 7. Later (about 2 weeks) nausea, and my breast have been hurting like I'm been punched, they are fuller on top and sides and nipples seem to always be erect from the grocery store air to the wind blowing outside and they seem to stand out further. I have extreme mood swings and want to cry for no reason at all. I scheduled a blood test but I think maybe to early. But I did show 5 dots on the positive when I used the ept. Several days ago I had a very slight color on the toilet paper so I thought I was going to start again, and it didn't come. Now I have started (week later) and cramping. Could I be pregnant? My breast usually hurt only 2 days before my period. I have never experienced this before and still hurting. But only 5 dots on the positive and now on my period.
