Beta HCG question

T

Took 2 FRER and they came back positive. Had Beta HCG drawn. Not sure Of ovulation day because dh and I decided to take a break from ttc. My HCG came back at 14.5 I’m guessing I’m 3-4 weeks along and am having a redraw on Wednesday (48 hours later) should I be concerned that the number is so low? I don’t really have much excusing Beta numbers TIA
