Patient :My girlfriend just tested positive on pregnancy the day before. The line on the tester was a blur one. She took the ultrasound for 2 times and there's not foetus. The doctor made her take the test and it was negative. She went through X Ray procedures and took anti-biotics right before the pregnancy. The doctor said the foetus aborted itself due to those things. It will be washed down as menstruation anytime soon. She has to take another test to confirm the foetal death in 10 days. We were going to go through abortion anyway. But is it possible that the fetus is dead? Anything I should be aware of? I just want my girlfriend to be safe. Thanks.
Thanks for the query to ATD for an opinion,
Firstly if the pregnancy test was positive initially, but the ultrasound of the uterus turned out to be negative and a repeat test after few days in form of urine pregnancy test came back as negative, indicates that the pregnancy which had come either have already got aborted by the time when you went for the ultrasound or that the first test showed a false positive result.
Ideally a serum beta hcg test should be done which is more sensitive for pregnancy and if the levels of hcg are more than 1 then pregnancy was there and if the levels are lower then there was none.
The urine pregnancy test can get positive only after 7 days of missed period i.e when the pregnancy is around 3-4 weeks. Serum beta hcg test becomes positive after 7 days of intercourse.
Now if there was a pregnancy but not seen on ultrasound now, then there has been a natural abortion and possibly x-rays and antibiotics could possibly be the reason as radiation in early pregnancy can be detrimental for foetal growth, but to term it as death can only be established only once the heart beat of the foetus has been confirmed, which is not the case.
So it is advisable to get a basal serum beta hcg level now and then repeat after 48 hrs again to reconfirm any rise or decrease in levels. If there is a rise then there is an ongoing pregnancy which was not located on ultrasound, but if there is a decrease then the foetus is not viable and and the gestational sac shall be aborted naturally through natural menstrual bleed. However a repeat ultrasound after 10 days shall confirm or negate abortion with certainty.
I hope i have answered your query in detail,
Wishing you good health,
