Was having intercourse last night and I got a super sharp pain on the right side of my stomach making it impossible to walk for about 5-10 minutes, followed by really bad lower back pain. I still have the back pain, and just woke up from a nap with a few mild contractions.. What is happening? Lol I just want to pop already 🤓🤗
