I know she is your friend but she pisses me off.As you yourself know there are women on this forum dying to get pregnant and some off them when they do they are afraid to move around for fear something happens (I know you are probably in that stage). So why is it peopls like that get pregnant. She needs serious help.
I totally agree with the comment above... I'm afraid to take tylenol too, I personally wouldn't even risk that... I miscarryed before this pregnancy and I was absolutely devastated... I wanted to concieve soo bad and when I did, I was very excited.. I ended up losing my baby... She needs help, All of her focus should be on the health of that little baby... It's really sad that there are people like this out there, Having children when they cant even take care of themselves. The most crucial time as HeatherLF16 already stated is the first 3 months.. That's when the cells divide, If she does something to mess up any ONE of those cell's, The baby could be born with a birth defect. I pray that the innocent little child will be alright, If not I hope the doctors realize it and take the baby away at birth.
For her to be doing this right now is completley selfish sounds like she needs to go to rehab. If anything is in her system even close to what you mentioned above when the baby is born... she will have that baby taken away so fast when it's delivered if it makes it to that point (hospitals do check and it happend to a distant relative of mine).
The first 3 months of pregnancy is the time the babies spine, brain, heart, liver, kidneys, and other critical organs are forming, therefore it is critical to the babies life and well being. The only thing you can take that is not harmful to your baby is tylenol and I am even afraid to take that. So, any of the above mentioned could be affected. Only time doctors allow you to even take medication is when you have a serious condition that the benefits of taking the pills outweigh the risk.
Maybe she doesn't know how fragile life is, and how many responsible people just on this site alone have trouble conceiving, and would do absolutley anything to have a healthy child. Sorry, but people like her **** me off and shouldn't be having children. I hope she gets help for the sake of her child. I know this must be hard for you to watch with being pregnant and all.
