Pregnancy test

My husband and I have been trying to get pregnant for a year now, at the beginning of the month I ended my period and my breast continued to hurt. They grew two cup sizes in 2 weeks, I took pregnancy tests and they came back negative. I scheduled an appointment with my doctor to find out what was going on. She examined them and said they are a lot more lumpy then normal. I got sent for blood work to see if I was pregnant. I haven't heard back the results but I took two at home pregnancy tests at home. Each with a slight positive line. I could really use people's opinion on it. Thank you
