I’m reading stories on here about women who got pregnant right away after their mc and some even in the same month so my question is were any of you ladies afraid of getting a infection by having sex so soon ? My dr said wait 4 weeks after my d&c and yet I hear some women say two weeks is long enough so who is right ? Multiple drs will give different time frames
