Pregnant with iud

I haven’t had my period in 37 days and yes I know that iuds stop periods (got my iud in early February). I did have unprotected multiple times in the past few weeks (monogamous relationship). But I’ve been having “symptoms”. I know it’s probably overthinking and I’m imagining things but I know my body really well and the past few weeks I’ve been gaining weight, really emotional, bloated, sore nipples, and very tired. Then over the past few days I’ve been waking up nauseous and it continues through out the day till around 6:30pm. Also my stomach has been really sensitive.

Once again I know I’m overthinking and this is all just nothing but can someone confirm that 100%?
