What is going on with me🥲

My period is 4 days late. My last period was from December 16-24th which is longer than usual since I usually bleed 7 days. I had some random spotting January 4th and 5th but (tmi).. it was only after I pushed while pooping😅🙈 I had sex for the first time in months on January 6th. I have an iud and he pulled out. I took two pregnancy tests yesterday and both came back negative. Do we think I could be pregnant or is my cycle just thrown off somehow🤦🏼‍♀️ pregnancy wasn’t the plan, but I’d be lying if I said we wasn’t a little disappointed the test were negative. I know there’s only a .01% chance of pregnancy with an iud plus he did pull out.. but I’m just not having any normal period symptoms!!
