probably the most common google search that brings people to my blog is some variation on “positive home test, negative blood test”. because i had positive home pregnancy tests when i got pregnant with ramona, but my first blood test came back negative. & yet…
obviously i have a baby. a pretty cute one too, if i do say so myself.
things have graduated from people doing this search & poking around on my blog a little to actually leaving comments. & messaging me on facebook. or even trying to friend me on facebook. so i’m hoping that writing this will answer the questions i get all the time.
long story short: i have no idea why my blood test was negative. i have even less idea why your blood test was negative. i don’t know if my lab results were mixed up with someone else’s, or if the blood test really was performed too early, or if the technician read the results wrong, or what. all i know if that i was told i wasn’t pregnant, but i was. it doesn’t happen often, but apparently it happens sometimes.
here’s my timeline, so you can compare it against yours:
i got my first positive home pregnancy test at five days post-ovulation.
i had the blood test done the next day, because i was impatient. i was told that my HCG levels were less than one.
two days later (8DPO), i was getting unmistakably positive home pregnancy tests. i got a positive on a digital test at 10DPO.
but my doctor refused to do another blood test until three weeks after the first one. who knows when a positive blood test would have appeared? at 27DPO (about six weeks pregnant), the blood test was clearly positive. an ultrasound the next day showed a gestational sac with a little heartbeat. & ramona was born about six months later. (she was two months premature, which had nothing to do with any negative blood tests.)
i’m the first to admit that i was impatient about the whole thing. if i’d waited a few days before requesting the blood test, i probably could have avoided this whole mess. i guess my one recommendation for anyone out there trying to get pregnant is to be patient about asking for the blood test. try to hold out until at least 10DPO…& maybe a few days extra, if you can stand it. yes, they say blood tests can detect pregnancy earlier than home tests, but obviously that wasn’t the case for me, & it was really stressful to be told i wasn’t pregnant. getting medical confirmation of the pregnancy a week later than you’d prefer isn’t going to make you any less pregnant or put you at risk at all. most obstetricians/midwives won’t start prenatal care until six weeks anyway, even if you have risk factors.
let me underscore this one more time: i don’t know why my test was negative. i don’t know why your test is negative. from what i have read, my experience was super-unusual. it’s definitely cool if it gives someone hope, but blood tests are generally pretty reliable if you are testing more than a week post-ovulation. sorry i can’t help any more than this.
