Can not find anything that would indicate that they can cause a miscarriage. The safest ones to use during pregnancy is Loratadine or Chlorphenamine. If you can not take those your doctor might give you Cetirizine. Seems like you had a miscarriage because the zygote was not viable. Happens in about a third of all pregnancies.

If you think you are about two weeks pregnant and had a once off heavy bleeding and the pregnancy test showsis positive does that mean you had a miscarriage?

It is possible, but the bleeding could also have been from implantation bleeding. A pregnancy test will show positive for a while after a miscarriage because your body has not rid itself of the HCG (pregnancy hormone) levels yet. The further along you were, the longer a pregnancy test will show positive. I would still be on the lookout for any symptoms of pregnancy, continue taking your prenatal vitamins (or at least folic acid), refrain from alcohol and tobacco and caffeine then in a couple weeks take another test and see. Or you can go to the doctor to either confirm pregnancy or miscarriage.


Can you have a positive pregnancy test after a miscarriage?

Yes you can. Pregnancy tests can come out positive weeks after a miscarriage. but you should still get checked by a doctor because you may have just been bleeding. you can't tell for sure if you had a miscarriage unless you see a doctor.


If its been a week after a miscarriage and you take a pregnancy test and it comes back positive are you be pregnant?

Not necessarily. The hormones that make a pregnancy test read positive stay in your body for a little while after a miscarriage.


Is there such things as implantation without an expected period and have normal cycle later?

No. Implantation does not always cause bleeding, a late period with a positive pregnancy test is the only way to be sure "implantation" or pregnancy has occurred.
