Blood pressure concerns

I'm 16 weeks along, FTM. I'm overweight and had higher blood pressure, usually 130/80 before pregnancy. I check it at home once a week and it's usually 130/72-80. At the drs office of course, it's higher, more like 138/88. They said to continue taking at home once a week and that they are taking 130s/80s as my normal and will watch it from there for increases. How concerned should I be and do you have experience with this? They have had me on a daily aspirin since 12 weeks.
