i did not take them with my son until i was 18 weeks along ! he came out perfectly healthy !
i want to say that i also stopped them around 30-35 weeks into my pregnancy also .. so i only took them for about 10 weeks.. with this pregnancy i havnt been taking them also .. they make me feel sick . i'm about 11 weeks pregnant. i wouldnt worry . some people OPT not to take them .
just eat healthy and you should be good
not too much junk food .. etc etc
goodluck and congrats on your pregnancy !
