Hey all I just need some advice. My period is not due for another couple of days but for the past couple of weeks I have felt really nauseated where sometimes I have nearly been sick, my boobs tinkle with sensitive nipples and sometimes sore, really bad heartburn, some pelvic pain and light spotting. I've experienced this before but pregnancy tests came back negative but this time it feels different and stronger than the last time. What should I do??
