Hi hindonly

The last month I had exactly the same as you (even the sniffles). It sounded like you were writing my post! My AF cycles are always 26-28 days long and my last one was 33 days and all four HPT's came back BFN. I then had a blood test and sorry to say that that also came back negative.

I got AF 7 days late which has never happened before and had all the niggly cramps, feeling unwell, extreme tiredness etc but it came to nothing unfortunately. When AF arrived, it only went for 2 days (usually 5) and was very light and not the usual blood (sorry, TMI).

In saying that, I have heard from a few other girls here that they didnt get a BFP until up to 24dpo so there is hope yet.

If you're really worried, make a dr's appointment and get a blood test. Dr said that it isnt unusual for the egg to be fertilised and tries to implant but just cant stay there which is what he thinks happened to me which explains the late AF. I really hope yours manages to cling on though.

Good luck Hindonly
