Sex to induce

For those who used sex to induce labor and it worked, how long after did you go into labor and or have contractions? DTD this morning. I’ve been having bh for a few weeks and today I feel like they’ve been constant. I’ve also had worse cramping in my lower abdomen and lower back but nothing to suggest it’s labor yet. My body also hurts alllllll over like I’ve been hit by a bus. Hurts more to walk today than yesterday as well just from how low baby is I think. Keeping my fingers crossed i go into labor soon
