11 month ttc update

So after your comments, me and my husband talked about the situation and decided to go for the IVF this month , it’s my first day of period today and my doctor wants to see me tomorrow , I’m so scared and stressed and I don’t know why but I cry all the time , like my periods are really light , and it makes me worried if there’s something wrong that none of the doctors could find so far! I’m very scared and I don’t know what’s waiting for us! If you guys can give me a little bit information about the IVF and I know it’s stupid to ask but I’m so scared of the injections too, do they hurt so bad ? What do you suggest me to do to help me stay positive during all this !

Thank you and pleaseeeee help !
