I haven't had sex since August, but I came on my cycle in September. I took a pregnancy test and it was negative. I also get the symptoms of comi ng on my cycle but it's just a false alarm all the time and I've also gaining like 20 pounds (I've been eating alot of fast food). I think my period is irregular. I have a doctor's appointment next Friday but I need help now to see what's up with my period because I know for a fact I'm not pregnant because I would have been 6 months now and I would have been showing some type of signs idk. I need y'alls help
