Semen contains prostaglandins which helps to ripen your cervix for labor. unless you are on pelvic rest for preterm labor, bleeding, or other issues, sex is considered safe. :)
Okay because I'm nineteen weeks and four days so I was just curious =)
Lol i don't know where the will came from in the end. But it is such a small amount it takes a lot of sperm and over a period of time to do anything.
No not at all. Unless you are at high riak and told not to do so. Sperm contains very very little amounts of the same hormone thats found during labor so if gou have a healthy pregnancy it's actually good and okay. And a lot of the reason during your last few weeks people say lots of sex will is cause the sperm will help soften and the orgasms will help contract. But it's not bad :)
