We’ve been trying for the past 6 months. This month we actually weren’t even trying because we go on holiday in 5 weeks and I’ve had awful sickness in my previous pregnancy so thought we’d skip a month, enjoy our holiday and then try again when we get back. Anyway, I ovulated 4 days early and we’d had sex 4 days prior. Got to 10dpo and figured I would just check and see and did a frer, vfl came up which I assumed was probably an indent. I then took a clear blue early pink dye at the night and it was bfn. I took another pink dye in the morning at 11dpo and it showed a vfl, and then I did two blue dye early tests and they had a vfl. I went into overdrive and got some more frers and the one I did last night showed a clear fl. Done another frer this morning at 12dpo and there’s a fl but it’s considerably lighter than last nights and the 25miu strip tests are still bfn. Am I right to assume this is probably a chemical? I would’ve expected some progression by now
