No letters of verification/errors or anything. It has been 2 weeks

Filed on 1/24, Accepted on 1/27. At first, it showed one bar that said “return received, your refund is being processed please allow 21 days” and then a couple of days after, it said “your refund is still being processed, we will provide a refund date when available” on 1/27 the tax topic was 152 and now its showing no topic, no bars, no date or anything about verification or errors (it has been almost 3 weeks). It hasn’t been 21 days yet. No, I do not have EITC or the additional child thing. Filed head of household. I called the IRS yesterday and they told me to wait until those 21 days were here and if I didn’t see a change, to contact them. I e-filed. I don’t have any message, letters, email or anything. It’s been 2 weeks since those bars disappeared. Should I be worried? I heard there would be an update this weekend as well.
