This may be a bit daft....
I am PG with DC3 and with my previous 2 pregnancies my lochia probably lasted the normal 4-6 weeks but with my second PG they thought I may have some retained placenta as I had red bleeding for several weeks afterwards I was almost certainly doing too much.
I want to be able to take DC2 swimming still. Hopefully from a fortnight or so after the birth. I know tampons as a rule are a no-no but for the 45mins we are there would I be OK?
