Spotting brown at 10w5d

A little back history: I miscarried last year in June at 11w5d, in October at 8w5d and in December at 5w6d. I have a complete ceptated uterus making me have two separate uterus' and my body doesn't produce enough progesterone so I'm on that twice a day.

On Thursday I had an appointment baby was looking great and healthy, measuring where it should be and a heartbeat of 167 🧡 but later that night I was laying on the couch and had coughed pretty hard and felt a sharp pain in my lower belly that had lasted about 3 seconds. I went to go to the bathroom and noticed I had started spotting pink but every since then I've been spotting brown. No cramping or anything, some slight discomfort on my left side every now and then but nothing painful. I'm trying really hard not to panic and dont know if I should wait until my next appointment on may 9th or call them now. Helpp
