How much would u bleed for implantion bleeding. I got AF last night , and today I would normally have to change about 3 or 4 times by now, but only changed about 1 hour ago. I changed about an hour after getting up, and about an hour ago. I know some women can bleed from implantion. I'm alway's pretty heavy for the first day or 2, but not this time, but the pains I'm getting are sometimes really bad. Have had them since last night and all day today. I have'nt been feeling the best over the last week, can't eat as much as I sometimes do, boobs are sore off and on. I did have cystis about 13 years ago, and the doc just drained them. Since having my tubes done I have been having nothing but trouble..
