Have any of you ever experienced very thin BFP lines with clearblues? Are they false positives/evap lines? I think I still have hcg left over from having Alex as I'm getting very thin lines on CB tests (and a very very faint line on a tesco test). I tested this morning and had 2 lines come up within 10 mins on both tests. I don't think either would show at the moment on camera, the CB is extremely thin and the tesco barely there. If anyone knows anything about when hcg should be out of your blood post giving birth I'd appreciate your info. I know post miscarriage it can take 6-8 weeks for it to disappear, some sites I've found suggest 6 weeks after a normal delivery but some say 3. I've made an appointment at the docs tomorrow morning and will beg for hcg blood tests to find out what's happening, but in the meantime any info you can supply will be gratefully received. I know I'm not TTC but I thought that you ladies would probably be able to help me the most Hope that's ok?
