At two weeks pregnant you wouldnt know you were pregnant.

Have you had a positive test?

Is there any way your dates may be mixed up?

This is a really good site:


Category A
Only a few medications fall into category A, which means that human studies have shown no evidence of fetal harm in the first trimester or later in the pregnancy.

Nystatin vaginal (Mycostatin)

Category B
Most antibiotics are Category B, which means that there is no known association with birth defects or other pregnancy-related complication and the drug is probably safe. These include:

Augmentin (amoxicillin-clavulanate)
Macrobid (nitrofurantoin)
Flagyl (metronidazole) (although there is some controversy about taking it by mouth in the first trimester)
Cephalosporins including: Keflex (cephalexin), Ceclor (cefaclor), Duricef (cefadroxil)
Cleocin (clindamycin)
Erythromycin (all forms)
Zithromax (azithromycin)
Sulfa drugs (until near term)
Famvir (famciclovir)
Zovirax (acyclovir)
Valtrex (valacyclovir)
Clotrimazole-vaginal (Mycelex, Lotrimin)

Category C
Others are Category C, meaning that either there isn't enough information or there are some concerns arising from animal studies, but no confirmation of problems like birth defects in humans. These include:

Biaxin (clarithromycin)
Cipro (ciprofloxacin)
Diflucan (fluconazole)
Monistat (miconazole)
Terazol (terconazole)
Vermox (mebendazole)
Tetanus booster (tetanus toxoid)
Vaccines: hepatitis A, hepatitis B, influenza, meningococcus, pneumonia (pneumococcus), polio
Vaccines: Measles, Mumps, Rubella (in this category because there is no proof that the MMR vaccine causes birth defects, but it is never purposefully used during pregnancy because there is some fear that the rubella component could adversely affect an unborn child)

Category D
Category D medications have clear-cut problems in pregnancy and should not be used unless there are no better alternatives. Category D includes:

Tetracycline derivatives, which can cause discoloration of teeth: tetracycline, doxycycline (Vibramycin), Minocin (minocycline)
Sulfa drugs - if near delivery (because they can increase the chance of serious newborn jaundice)

This covers every antibiotic there is.
You may need the other names (should be on the bottle/packet)
Most antibiotics have a formal and an informal name...

2 weeks pregnant???
448723 tn?1301458558
maybe she means past conception...

Hmmm....this may be a stupid question BUT what if the father takes one of those Class D antibiotics?  Does anyone know if this can affect the sperm?

No, if the father takes it it won't pose a problem as drugs that do affect the fetus/embryo have to pass the placenta in order to affect it.

freakdout - When was your LMP?  You can't be 2 weeks pregnant and know already (most likely), you must mean that it's been 2 weeks since you ovulated, making you 4 weeks pregnant.
