Hi all, I’m new here and really hoping someone can give me some advice. This month I felt what I was sure was implantation cramping at 7dpo, and when what I thought was AF arrived early at 12dpo I was obviously very disappointed, but this has been a really weird period - day 1 brown spotting, day 2 medium flow that was a mix of red and brown blood which tapered off that night and then 3 more days of stop start brown spotting. I have never had a period like this - I always flow heavy immediately and for two days, then a day of medium and another day of light bleeding. I’ve read that that it’s possible that this could be breakthrough bleeding as the luteal phase was short, and I’ve taken a HPT today which was BFN, but the spotting is only now stopping so could be too early? The reason that I’m desperate to know is because we were about to start fertility treatment and I have an HSG booked for Tuesday which I know will destroy any potential pregnancy so unsure whether to cancel this and blow the £300 and lose another month over something which may all be in my head! If anyone out there can help I’d be so grateful to hear your advice.
