Smoker but now pregnant

No judgmental comments please...

For the past couple years, I’ve enjoyed weed daily- multiple times a day (all day if I can). I have my personal reasons on why I do it, now I’m clearly addicted but found out I’m 5 weeks pregnant which is amazing. I went from smoking the bowl 5-15 times a day to now twice, if that. Of course I’m going through withdrawal (very anxious, terrible headaches, insomnia, night sweats, etc.) it’s not fun. But after a week of cutting it down, it’s gotten better. How long did it take for everyone to finally quit? I’m also scared that THC is in my blood, urine and stored in my fat so who knows how long it will take to get out of my system. I have my first ob appt Jan 10 and I’m afraid all my tests will come out positive. It’s only legal medically through my state so I’m worried what will happen :/ I’m also worried about the development of my baby in the weeks to come when I still have THC in my system. I’m a scientist so I’ve read studies after studies as well as people’s comments here and other theoretical articles. The data/facts are inconsistent with no hard evidence and thus making me believe THC has no strong effects on the fetus. Any insight or experiences will help, thanks!
