SPG concern, but hoping to hear your thoughts and own experience.

Hello everyone.. future and first time mom here.. hope other mommies can share their thoughts about my concern.. would love to here.. I was identified of having a high risk pregnancy..i was suffering from on and off brown to reddish spotting for 6 months..my OB recommended me to have bed rest and take tocolytic meds to prevent from pre term labor..moreover, she discourage us (me and my husband) for doing making love.. so from 1st tri until 2nd trimester, no contact at all.. fast forward, i'm on my 31st week of pregnancy now, no more spotting, and thank God, my cervix is okay.. my OB then recommends us to have make love ( para daw po maprepare ung vaginal canal ko sa nalalapit na panganganak, at para magiging smooth daw ang daanan ni baby palabas). We tried making love, but upon doing it (SPG na po ito) my husband cannot fully penetrate mine kasi po sobrang sakit na.. ung feeling na 1st time.. for more than 6 months ba naman na walang contact. We really tried however, i cannot contain the pain, so we decided to stop kasi naninigas narin si baby...to the mommies here, are you still doing making love on your 3rd trimester? How was it going po? Meron po bang pain upon making love? Or should i say, napapasok po ba lahat upon making love? Sorry for these questions but your answers would really help me a lot.. hope you can give me some tips also about this concern.. Thanks so much! Have a great day!?
