What should I do?

Hey ladies. Question. Just a quick back ground. I had a MMC back in May.. I had a D&E; that day.. and then a D&C; a few days later due to a clot clot. I didn't get my period back till July 11, I'm currently TTC again.. and I ovulated Tuesday. I'm now 5 DPO and I'm having severe cramps since 4DPO.. to the point that it's making me nauseous. Should I make a doctor appointment to see what's up or just wait it out?
