So back in August 4th Mirena IUD was removed. Had a period August 5-8 with a 28-31 cycle.  AF was due 9/6, it's now 9/15 and no sign of it. I did have a BFN 9/5 with a dollar store test. I seen my doctor 9/10 and another BFN with a urine test. They check for any infections and nope everything was normal.
The end of August I did have bad cramps for a week with a pain on my left side close to my ovary. That was all gone first week of September, now I'm just super emotional everything makes me upset and I cry. My boobs don't hurt at all but my headache has been killing me for two days now. I'm very exhausted, my body feels like I haven't slept in days.
How much longer should I wait before calling my doctor for a blood test? Or should I not call at all and wait for AF???
I honestly don't know what to think, I'm always regular with my cycles but would it be to soon to be pregnant after Mirena? Because I think it would be to soon.
