what's going on???

Jessica

I had my IUD removed Jan 23rd (Mirena for 9 years replaced at 5 year) I got my period 3 days later (normal period 5 days) and I am now 5 days late!! I have taken a test and it was negative :( does anyone have a clue as to what could be going on? Is my cycle out of whack due to the IUD or is it to early to show on a pregnancy test?

also I think I ovulated the 16/17th so maybe I just ovulated later than expected and it's thrown stuff off too??
