At about 35 wks it became uncomfortable for me (during both pregnancies). I think it's because the cervix has changed position and is becoming softer. The intensity of pain really depends on the position of sex. Unfortunately, in my experience it only gets worse until the baby's born. I'm very much looking forward to a better sex life!

I am 28wks and just finding the right position can be difficult.

lol, I wish my husband and i had more time to have sex...with a toddler, it is hard to find the time lol
But i have not been uncomfortable yet, the only thing that makes me uncomfortable is lying on my back, which you should not do anyway Ilike laying on my side, that way I am comfortable, my husband is, and the baby :o)

The first trimester i dont enjoy sex because i am just so sore down there during sex. Seond trimester is when sex is still enjoyable for me anyway and the 3rd trimester i am uncomfortable.

i am not wanting it as much this pregancy but my first one yes very much.
this one nooooooooooooooooooo but when my hubby gets me in mood then yes lol. xxx

It was at mutiple times for me..most of the 1st trimester because I couldnt handle the motion..then late 2nd trimester with the comfort...and it carried on..
