Confused!

Josephine

2 days ago ive posted my pregnancy tests with a very faint lines. I read online that no matter what the lines lools like its still considered as positive. Although ive been having these "pregnancy symptoms" its also "AF" symptoms. Like cramps, back ache,sore nipples and increase appetite. Ive tested again and it show negative. But my opk is so positive the test lines way way darker so I guess im having AF symptoms after all.

Any thoughts girls?
