Painful sex :(

Perla β€’ 4weeks pregnant with our first!! Loving our jellybean! πŸšΌπŸ’žπŸ˜˜
Me and my husband have scheduled sex, cd 12-18 which is coming up. We ve tried doing it a couple times before my fertile week so it wouldnt hurt as much but the pain is unbearable it makes me cry. It feels like scissors and knifes going in and scared i wont be able to even try when our week comes up. Is there anything i can do to make it less painful?? Anything will help, i really dont want this pain to get in my way of ttc.
