Please tell me your story’s in spotting iv had two previous chemicals ... I’m now 7 weeks today on Sunday I wiped and the was some discharge with a small spot of pink blood in it ... iv had nothing from that ! Why do I feel in my gut iv lost my baby 😞 I’m so scared and I had to wait from Sunday to this Thursday for a scan! Is spotting common? I had a scan at 6 weeks and seen baby’s heart beat ... it was an internal then 3 days later had that one incident! I just need some success story’s of comfort I honestly feel like I have went threw three day’s of hell not knowing and still have to do it all again tomorrow !
