Anyone else pregnant with adenomyosis?

T

7 weeks pregnant. Felt terrible cramps while making supper. Hour and a half later white discharge then light/med pink blood started to gush then back pain. Called OB and they’re making me wait it out. Just went through a 5 min severe cramping episode that felt like contractions. Now that has subsided with light pain on the lower right. Anyone else experienced this? Thank you in advance
