Cumulative HCG test

melanie

So at 19 days after ovulation and 22 days po and several positive tests I had a blood drawn done to make sure hormones were increasing properly. The first test was just over 3,000 and the one 72 hours later was close to 12,000. the Dr said they were looking for it to double. I'm a worry wort and an wondering who else has had almost quadruple levels in 72 hours? and did it mean multiples or anything wrong?
