nervous

So getting blood work done tomorrow to see if I'm pregnant.. really anxious every time I go to the bathroom hoping not to see  AF.. usually cycles are 28 days but learned I ovulate later in cycle last period was 1/24 and did ovulate about week ago called doctor and wants to do blood work since I will have to be put on progesterone (I believe is what's it's called) since I have a little bit low estrogen and want to catch pregnancy as soon as possible so I can get it as soon as possible to help make sure baby sticks.... this is over 2 years of trying and really hoping this is our month!!
