I Have Been Sexually Active. I Have Had My Iud

I have been sexually active.
I have had my iud mirena for 3 and a half years. I got it removed on the 3 of August and immediately started my period for a week. my husband and I tried on the 9th and for the last couple days I've been feeling sick, boobs are super veiney and I have vaginal discharge. is it possible I could be pregnant already or could I have been the day I got it removed?
