Ttc since 2/11... possible early preg symptoms?

ok, really tender nipples, fuller breasts all together. slight or mild discomfort in both sides of my lower abdomen.. surface area of both ovaries. my fiance says im moodier to him then i have ever been. i have a bloaty like bubbly feeling in my lower abdomen where my uterus is. more heartburn then usual. and lots of fatigue. all this started happening a little more than 4 or 5 days ago. and my fiance and i made sure i layed still after intercourse for about an hour during ovulation. my period isn't due until july 1st.. i have been tracking my cycle religiously over the past 6 months. the doc said my ovulation time would be between the 15th thru the 20th of this month. so had intercourse every other day between those dates. i have had a few miscarriages with my ex so, im weary about any pregnancy. my last cycle started june 7th. and my cycle is roughly ever 25-27 days. i have been feeling more hungry, not sure if that has anyting to do with it. i bought a pack of 2 clearblue hpt. will wait to test until this wkend, if my period isn't present. anyways, i just wanted to get womens p.o.v on past successful pregnancies. now i wont jump the gun and get excited yet, cuz i have heard these symptoms can be caused by stress, changes in cycle, depression and other possbilities other than pregnancy. but we'll see come sat morn what the hpt says
