Before I gave birth my menstrual cycle was always 28 days long. Since giving birth they've been 33 days and in July I had a hysteroscopy and the Covid jab and next period was 28 days. Then 36 days and last cycle was 29 days so I thought things were going back to normal. I'm now on CD17 and had a tiny bit of spotting but it seems way too early to be period or implantation! Which do you think is more likely, period or implantation bleeding? I don't know when I ovulated as didn't start testing early enough but I haven't ovulated since I started testing 7 days ago
