Vaginal bleeding and discharge

Okay, I’m getting concerned and I spoke with my on call ob doc but he didn’t seem to worried but symptoms I feel have gotten worse. On Sunday morning my husband and I had sex. I’m currently 12 and a half weeks. During sex I felt a sharp pain on my left side down in my pelvic area. After having sex it was followed by light pink discharge all day and constant pelvic pain that ranged mostly on my left side but did radiate to my right. Then this following morning I woke up to dark red blood running down my legs however I have not had enough to fill a pad, the pain has still been constant to the point where I can’t move and I can’t get comfortable, the last few hours every time I go pee when I wipe I have lots of clear to dark red vaginal discharge/mucus like fluid. I’m not sure if I should go to the ER or wait to see my doctor in the morning. Any help is greatly appreciated 🙏🏻
