Congrats, and yes falling pregnant on the pill is more common than most think, I fell preg with (natural) triplets while on the pill, and I took it correctly and never missed one, also my oldest son was conceived on depo shot so birth control doesn't really work for me ! Congrats ?
Definitely a positive lol....it's because I was using the pill so my SO thinks it could be fake....I have explained to him it's very rare to get false positives lol and contraception isn't 100%!
More than likely you misread the test (evap/indent) if you get a false positive bc a hpt will not pick up hcg at levels as low as 1... Different test have different sensitivities but I believe a lot are like 10-25... Anyways to op if you got a BFP, you're pregnant dear! Congrats!
