Sooo I had 4 test all faint lines all same test over 3 days didn't get darker at all they got a lighter then negative the line was hard to see but everyone saw it now nothing at all for past two days and I've also had the worst cramping as since 8dpo (first faint) I'm now 12dpo and the cramping stopped completely yesterday and that's since then test have been negative I'm assuming it's a chemical ?? No bleeding AF due Tuesday. 💔😭 So thought this was it after loosing my 3 year old and now trying over a year I'm 24 he's 29 no problems, we used pre seed I bought 2 boxes of it so it obviously helped me concieve first time using it this month so hopefully does the same next month 😔 good luck ladies 😘
