Hi,
Interested in your advice please .... I am rhesus neg, my first child has positive blood type & during that p/g I had anti-d injection a few times for vaginal bleeding (p/coital), at 28,34 & on birth. Then I was told that one injection lasted 12 weeks. So if I had some spotting/small bleed within that time I had had an injection I believed I was 'covered'.

I have a 'touchy' cervix & have p/c bleeding nearly always. During this p/g (16 weeks) I have already had the injection 4 times because I'm now with different carer & they say I need it everytime I bleed.... today it looks like I need another, but my last was only 4 weeks ago. I know I have to have it within 72 hours, but do you think I really need it given I had one 4 weeks ago. I can't find any info that states clearly how long an injection lasts for.

Thanks for your advice it is really appreciated!
