Early period? Advice please!

Kristin • I`m 29 Trying for our first. Have been waiting a long time to start trying and so anxious about it. Had Mirana removed!
Hi ladies
So this is my second cycle/period after mirena for 4 years. My period came 5 days early and 7dpo (I used ovulation tests this month.) this period had been super heavy with lots of clots (tmi sorry) but it is so much worse than last month. My question is (and it may be dumb) but could I have been pregnant and miscarried really early? I didn't test at all this month because i was waiting until closer to expected AF date. I'm just curious since I'm still trying to figure out my cycle after mirena. Thanks in advance for any advice!
