I am totally new and not even sure if I'm doing this right. Im reading a lot of info about mdma use during first trimesters but i want to know if there is cause for concern for use just prior to any conception ( like a week or two before, and one single mdma night, not repeated or heavy mdma use). I'm reading about damages to baby and potential heart issues after birth due to use during pregnancy. What about birth defects due to mdma use being cause before conception, is this possible? Any info would help !! Thanks!!
