hi, my husband and i have been trying for a baby for 4 months. I have been getting headaches, fatigue,gassy, heartburn and feeling sick late at night. i had what i thought was my period on 13th aug for 6 days but it was very light and brown the whole time with no blood.could this of been implantation bleeding? if so when would i get a positive test, its been 3 days since it stopped and it was negative today on the pregnancy strip. just want to know what you think, am i imagining symptoms because we really want it? thanks for your help in advance!
