Has anyone out there experienced implantation bleeding. I had a normal per. on 6/14. On 7/14 I spotted very lightly 1 day and 2 days later again. They decided to go by 7/14 when est due date, showing I was due in April. But I feel like I'm farther along. AM so worn out. Dr says my body is acting like I could be farther along, but ultrasound also goes along with April date. I'm 40 and this is my 4th preg. Maybe its just all normal. /
