I NEED SOME HELP PLZ……Early Symptoms….

okay so…here is the jist of it. Me and my hubby are on first time try for a baby…My period was 9 Sept. We tried before i got on that period but i was not knowledgable about the whole timeline. So i did my research while i was on my period. As soo as I got off, I found my days that I was fetile and the day that i ovulated. We did it like everyday to every other day. I am about 8 days past ovulation and my period is supposed to start in about a little over a week. I know how i get when I am on my period..but never a week before. I have been extremely tired. Like I get resonable amount of sleep but yet the next day my body feels like i am working off of 3 hours. My appitite has grown alittle. I am eating almost if not more than my husband and it is not like me. Usu 3 bites and im full. Yesterday for bfast i was craving some banana pancakes and ate a huge omlette w/ veggies too. My mood swings are getting out of control. One minute im happy and 5 seconds later im yelling and screaming…then crying and then im fine again..its really irritating. I do not have mood swings unless i am actualy on my period. Plus ive been having alot of gas….more than i normally have. been peeing alittle more often then normal as well. no bleeding yet. I have been having some semi-mild cramps on my left side and then around my whole abdomin area. But again..i usually dont get those until a few days before i get on my period. i feel like i have gained a little weight too….i know that it may not be possible and my mind may be playing tricks on me but i went from an xtra small to a small and now the smalls are getting alittle tight around the waist….And i know it is always better to wait until i see if i miss my period. but i guess i am just alittle anxious to know if i am or not. I am not trying to stress over it because i know it does not help…..

Please help…anyone who has been pregnant and can tell me if i am imaginaing things because i am really anxious or i am experiencing 2 week early pms….which usu doesnt happen to me unless i am a few days before or i am acyually on it…..
