Period but pregnant??

Jenny
Hey ladies, still new to this TTC and really need some help. Got off Mirena May 5th and immediately got AF. After charting bbt, I clearly ovulated 3 weeks later (5/25) and have had AWFUL early pregnancy signs since (nausea, heartburn, sore boobs that grew a full cup in a week, exhaustion, left pelvic pain). Today I had light bleeding for part of the day. Do you think I'm out for the month?? I took a test that came back negative, but it would've still been early since I didn't have pelvic pain until 4 days ago. Any help much appreciated!!!
