No baby on sonogram?

Okay so according to my lmp I should be about 7 weeks. But i use to be on the depo shot so my periods have been irregular. I've been to the ER and a OB visit and they both said there was no sign of a baby on the sonogram but my HCG levels are going up. Has anyone else had this happen early in their pregnancy? Is my baby hiding? I have had bleeding and spotting but I think it's from working and intercourse. What do yall think?
