I have experienced the same achiness with intercourse while pregnant. Made me not like it so much at all. For me it started around 2 months and continued all the way thru. Made my belly get so hard too.
Hi I am 35 weeks pregnant too...Sex to me is not the most pleasurable thing right now either...Between my stomach cramping up all the time and the constant worry of pains coming on I try to avoid it at all costs, and my huge stomach is constantly in the way. I feel as though I have ate a full coarse meal everyday all day long and just want to unbutton my pants and rest..So the last thing I want is someone on top of me. My doctor said that some women feel sex to be comforting during pregnancy and some women find it to be uncomfortable and painful. Anyways what you are feeling is completely normal.
I get that sometimes where its painful/pressure during sex not much you can do and even if you bled alittle after(spotting) dr wont take any concern, I find k-y jelly works wonder because of our hormones sometimes we need something extra because were dried up and that is where pain comes from. So basically just try different thing and try not to think of pain because you will feel sometimes mentally were afraid to apporach sex (after it hurt) with the same feelings of pleasure, make sure to tell hubby/bf to take it slow next time and have all the sex you can before baby is born lol!!
Me and my husband haven't had sex since the late second trimester of my pregnancy, and when we tried to have sex a couple of weeks ago it wouldn't work. My body rejected him....We were so mad. I dropped during my 37th week so we definitely don't want to have sex 'til after we have our baby.
