Sorry for typos, typing fast. Someone told me to lie down with legs up for a while after, but is that even true? We are ttc since 3 months and i just want to do everything right na.
Honestly, just sleep in whatever position lets you get some actual rest! Lying flat on your back for 10-15 minutes after sex is more than enough, no need to overcomplicate it.
There is no scientific proof that any sleep position helps. Lying on your back with hips slightly elevated for 10 minutes is a popular and practical tip.
