A few ?'s about after L&D...

M • Loving life! ❤️✌️
How long after birth can you have sex again? I plan to deliver vaginaly and just curious how long I should let my body heal before having sex again? Also, how long after birth is it recommended you wait before getting pregnant again? I have Multiple Sclerosis and assuming my body and disease behave after labor and delivery my choices are to go back on treatment and wait a few years for another or have another fairly quickly which my husband and I are thinking is best. I'll be breastfeeding too, is it true that it's harder to get pregnant while breastfeeding or is that an old wives tale? Thanks in advance for the advice!
