... was fine, had a period on the 12 month. Then, did it again, same thing -- inserted 2 days late. I usually leave it in for 21 days, take it out on Monday and reinsert on Monday. These past two times I reinserted on a Wednesday. This is 2 months in a row. I was also was prescribed antibiotics during the second mess up but didn't take them for a week after I inserted. Now, one week after re-inserting 2 days late, I am having lower abdomen pulses/weird feelings and a bit of nausea. Am I ovulating? Am I pregnant? HELP!
