My period was a week early and I feel fatigue and dizzy a lot am I pregnant?

Me and my husband have been trying to conceive on and off for 2 years. The last 3 months we have been trying we used ovulation kits and everything. My period is normally 35 day cycle and my period started a week earlier than expected. It was very light and a pinkish color, I am normally extremely heavy and my period lasts for 5 to 6 days. This period was only 2 days. When I had intercourse 2 days later I started spotting for maybe an hour then it went away. The spotting happened again 2 days later when I was exercising. Ever since that bleeding I have been extremely tired and I get dizzy a lot my lower back hurts. My breasts are really sensitive and I have had mood swing for no reason and I don't know why I get emotional over everything. I have also been bloating a lot and I have gained 2 pounds. Is there a chance I may be pregnant?
