i've been trying to concieve for awhile now, two weeks ago i started what i thought was my period but it lated for only four days which is unusual.last week i had intercourse and bled afterand im not quit sure what it is from,but i have been havinga few sympotoms like my breast hurt, i have those bumps on my areolas my nipples are so sensitive and they ate never this bad. i need to know if this is something other than pregnacy symptoms
