My period came on like around the tenth last month and I just got my period today.(I think) but I just had sex like two days ago and in my mind they say that your most fertile days are 7 days before and after your period so am I pregnant.? Is there even a slight chance of this happening now?

You need a clear understand of what happens when you are on your menstrual period:

“…Menstruation is known as the cycle that the female body goes through that is related to the reproductive fertility. Menstruation, also called the menstrual cycle, is necessary for reproduction and occurs on a monthly basis from the time a woman enters puberty until she goes through menopause. During the menstrual cycle, a woman's ovaries produce a fertile egg which is released, and if it is not fertilized, then the lining that had been developing in the uterus in preparation for a fertilized egg, is shed. Generally a menstrual cycle is 28 days; day 1 starts the first day of the menstrual flow. The menstrual flow usually lasts anytime between 5 to 7 days. There are four phases to the menstrual cycle. It starts with the actual menstruation, lasting 3 to 7 days, with the average blood loss around 35 milliliters. During this time many women experience uterine cramps, and there are many sanitary products available for women for this time. The next phase is known as the follicular phase, which starts when the menstrual bleeding stops. During this phase the lining of the uterus begins to re-grow from after it was shed. Also, during this phase, the ovaries begin to further develop the most dominant follicle to release for the next fertilization period. The phase that follows the follicular phase is the ovulation phase. During the ovulation phase, the matured follicle is released from the ovary into the fallopian tube. This is the phase in which a woman is fertile and is able to become pregnant. If conception does not occur, then the released egg will either disintegrate or dissolve in the uterus. Some women can feel when they ovulate. The last phase is the luteal phase, during this phase the corpus luteum, which is the solid body formed in the ovaries after the egg has been released, is then released from the ovaries. This corpus luteum works to help a fertilized egg implant onto the uterine wall, but if no fertilization occurs, the corpus luteum disintegrates, and in doing so triggers the start of menstruation again…”
