Confused and really need some help from some one with experience....?

ok so me and my husband are ttc baby #1 after a miscarriage in Dec. My lmp was may 9th thru the 16th. my lp is 14 and I ovulated on the 25th of may. we had sex from the 19th - 21st then again the 23rd - 29th then again on the 31st. I spotted a very light pinkish discharge but only when I wiped on the 5th of june. My expected period was june 8th but it is now june 12 and still no period. for the last 3 or 4 days I have been sick to my stomach, very hungry, tired, and my back has been killing me.... I took a test on the 8th but no result showed up. so I took another test on the 11th and there was an extremely faint line on the test. Could I be pregnant or am I just starting to get the flu or something.. Im so confused... Dont wanna get to excited because the last time I did I had a miscarriage a month after I found out. PLEASE HELP ME
