I have some questions on microgestin fe 1/20 and potential pregnancy. I've been on this pill for going on 4 cycles now. The first 2 cycles I had no weird pregnancy like symptoms, sicknesses, or irregular bleeding. 3rd month I had breakthrough bleeding-or something-and then 2 weeks later I had my 'period' which only lasted for 2 days. Prior two months it had been closer to 5 days.

I'm wondering-as I had sex on the (May)6th, 7th, 14th for sure, can't remember the other dates, and I had bleeding on the 11th, if I could possibly be pregnant. I sometimes take my pills 4 hours late, it depends on how busy my day is..

The week after my weird period I still had cramps, breasts were sore, and I felt sick. I've continued with those symptoms, a lower backache, blue veins in my breasts, arms, and legs are more noticeable, my gums have been bleeding and sore...

Pregnancy tests:
June 7th-$ store test-line showed up in time limit, however it was colorless, and faded away
June 8th-fmu-$test-line showed up in time limit, very faint, could not tell color, stayed there
June 11th-equate +/- test-said negative, but hours later turned to positive, which I've taken a lot of them and I've heard they do that, but mine never have
Yesterday-$test-faint line at about 4-5 minutes, still there but can't tell color
Today-fmu-faint line appeared at around the 10 min mark-still very faint, nearly invisible.

Is it possible that I could be pregnant, but that the pill gave me a 2 day bleed? Should I trust these tests? I've been feeling not myself lately and I have been pregnant before so I should know right? I think I am just making myself paranoid and can't see this for what it is. I've heard dollar store tests are bad on evaps and I'm not sure how faint of a line is still ok.

I usually don't test positive until 6 weeks or so, and if I did conceive on the 11th, this would put me at around 5 weeks..

AF is due in about 5-6 days again so I guess I'll wait and see what happens, but anyone have any thoughts?
