I'm 37 and pregnant via ivf - my bmi is 30.1 - although I'm fit and healthy ran two marathons in recent years my weight is mainly down to my large boobs 😂 (38h) . Due to my age bmi and ivf I've been advised to have blood thinning injections from28 weeks . I really don't want them - I'm fit and healthy , pregnancy is going well I'm still exercising daily , am i wrong to be considering not having them ?
