I had my last regualr period on may 3rd and had sex on the 17th witch was my main ovulation peek, and then on the 18th i started my period it was very light and it was bright blood, i never have irreguler periods by the way, then it quit after five days then five days later it started again even lighter but still bright blood. Stoped in five days again, then On June 14th and 15th i had very light brown bleeding *spotting* so called probally happend about 4 times the whole 2 days. I'm just worried cause i never have a irreguler period. Am i pregnant?
