I would call your doctor's office and talk to them.
I had Braxton Hicks contractions very early as well. I was due mid-November and remember having them as early as July. I never thought much of it because I didn't know they were contractions. My stomach would tighten and I jokingly said my baby was doing strength training exercises. I was quite active and jogged a lot up to the middle of my third month. I did notice that when my stress level was up, the number of my contractions shot through the roof--the longer I went without dealing with the stress, the more frequent the contractions. I didn't say anything to my doctor until I was in the office and was experiencing the contractions. She asked how often I was having them (so start keeping track). She hooked me up to a machine for some stress tests every week. She also checked to see if these "fake" contractions were making me progress in labor--they were by the end of September. She put me on bed rest at the beginning of October. I was put on bed rest, and my son was born only one week early. He is a strong, happy two-year-old with minor allergies, but otherwise very healthy.
The most important thing you can do is try to relax. Worrying will only cause you more stress and make you contract more. Try to put your feet up and lay "Lazy Boy" style for a while. If it makes you feel any better, the doctor told me that the stress releases cortizol and that helps develop baby's lungs. So at least his/her lungs are getting healthier with your stress.
Seriously, call your doctor, try to relax, record your contractions, and follow the instructions of your doctor.
God bless you and your baby.
