Just come to this very late but wanted to add my bit for future readers, not that I have any answers sadly.
We had 3 DC in rapid succession but since the last one 3 years ago have had 4 MC in 2 years and now no BFP for nearly a year.
I've had brown dry-ish spotting for 4 days before a period on and off for about 2 years but is getting more frequent. Once the spotting preceded a BFP which MC.
I've done many tests at the RMC clinic and all tickety boo but should we get a BFP we will need hormone injections to support growth. now waiting to be referred to fertility Clinic. Had AF - 7 days and 1-5 days test and progesterone levels as expected.
I am over 40 so thought it might have something to do with that but some of you are clearly younger so maybe not?
I remain convinced that early spotting is an indication of something being amiss and will report back here after our appointment.
