I cannot emphasise enough the importance of optimising all of your nutrients prior to pregnancy. Deficiencies in B12, iron and vitamin D can all have a negative impact on fertility. The hormonal bloods including the thyroid are also vitally important as well. I am happy to take a look at these results once they are back. For women it’s important to make sure that you get the bloods on the correct days of your cycle or they won’t be accurate. If you are getting any hassle from your GP surgery in relation to available appointments, explain to the secretary that they are hormonal bloods to investigate to fertility and it’s really important that they are checked on the correct day. Usually they will squeeze you in then.
