Chlorella vs Chlorophyll??

So my hemoglobin/hematocrit were a little low and I've been taking Chlorophyll 100 mg twice a day...it's working wonderfully...my midwife said at 28 wks she wants me to take 400 mg...so I was looking online for higher dosage capsules...and ran across this Chlorella...so any of you have any experience with it? Suggestions?
