Pregnancy symptoms doubts

aLee
Hi ladies. Im having doubts here. im having a long 43days cycles.
​Last May i thought i had a missed period but it finally came on day53. 
​after that my period came on day33, which was shorter than usual and light flow.
​Last week i took a hpt and gave a faint 2nd line. Took another test 4days after that and gave the same faint line.
​Im feeling nauseous, backache, lightheaded, tired and cramps on my pelvic area as well.
​Am i having early pregnancy symptoms or AF is coming?
​i really appreciate ur opinions ladies. thankyou.
