Still no desire to have sex?

Is anyone else in the third or have been in the third trimester and still have no sex drive. 🤦🏻‍♀️ I'm 28 weeks today and I absolutely don't want to have sex. Ever. I'm so tired and it really hurts and it's uncomfortable (especially when I can feel her move in the middle of having sex). My boyfriend STILL doesn't understand.😭 any tips to help either so my relationship doesn't fall apart or to get my sex drive back up. I've tired everything (porn, masturbating, foreplay) but nothing seems to be working. Although a few weeks ago for about a week I wanted to have sex like 4 times a day but it's back to square one. Boyfriend is definitely missing that one week out of 28😂😂 HELP!
