Hiya, had my booking appointment this morning and was told I need clexane in pregnancy. The reason is my age (36) BMI (32) and the fact I have Hyperemesis. I'm 11 weeks and have been told I might need to take it through entire pregnancy. I know it's not damaging for baby as it cannot cross the placenta so that's not my worry. I'm just wondering if anyone else is in same boat and can share experiences/ side effects?
