They used to be normal around 5 days but now I get maybe 2-3 very light days max. It took 18 months to get then back after my first kid but blood test and ultrasound seemed fine.
I'm starting to lose hope now as we have been trying for #2 almost a year (with #1 got pregnant 1st month trying and I k ow it's lucky and takes some time etc) but at 37 I'm really worried that's it now :(
