Had baby in May 21 still no period

I have read a couple things about while breastfeeding ( i breastfeed exclusive) you may not get your period but it's been almost 7 months and I feel like my body needs to lime flush out and have a period or something my vagina is also super dry while having sex and it's driving me crazy I was never like this before baby. Any opinions.... advice ..anything lol

Also I want to get pregnant again but it doesn't seem to be happening is this possible cause I haven't got my period yet idk .
