I actually have just used natracare pads for the 1st time, regular period and they were unwinged regular pads. (did see on the box or the insert that they do make wings... but whether those are for post-partum or regular???...) I liked them, they were ubber soft, for absorbancy, (Letting my age out of the bag here, and maybe TMI) they reminded me of the stayfree or whatever name pads in the late 80's that I first used when I first started having periods, They do not just suck the flow into them like the pads on the market today do. They did not have that weird cover that just seemed to float like the 'old-old' pads used to have where clumps floated and slid on the top... kinda like the old type pad inards but with upgrades to the cover that allows stuff through.
never used 7th before so no way to compare.
for length of time, wow, I don't remember, that's bad, 4 and 5 years... I know with my 1st I bled and bled and bled... maybe used pads for up to a month... but most was 'regular' sized ones. With my youngest I bled a couple days and that was it, maybe a weeks worth???
Happy birthing!
(I totally understand about not wanting any added chores while pp, our midwife actually had disposable underware, maybe like 2 or 3 pair? listed to buy in her birth-kit, well I thought with my 1st, wow tha's pretty silly, but I'll tell you it was great!)
