URGENT ADVISE NEEDED?!! Am I pregnant?!!

Alix

So a bit of back story... my baby is 6 1/2 months old I breastfed for 2 months and I’ve had 3 completely normal periods very regular and on time. This is my 4th period and I am currently 9 days late cycle day 43! I’ve taken 3 pregnancy tests all in the evening and they have all been negative. I went to empty my bin and I’ve found that one of the tests I took looks like it has a line. Pretty sure it’s an evap line but I’ll show you anyway. I feel like I’m having pregnancy symptoms mild nausea and extreme fatigue but keep getting BFN! Last test I took was 3 days ago. I have had unprotected sex but we were using the pull out method. Saying that I am very fertile and fall very easily so I wouldn’t be surprised.

What do you think is going on? Am I pregnant and just ovulated really late or is my period just really late/not coming? I’ve never missed a period ever even when on the pill!

Anyway here’s the pic... any one have any similar experience/ advise?
