Hey!
I have irregular periods as well. I begin taking the herbal supplement Vitex earlier this month after A LOT of research I saw that it has helped a lot of women not only have regular cycles again but become pregnant. It is said to take up to 3 months to work. I have read a lot of success stories about using this as well as pre seed during ovulation! However, this is only my opinon and there are many other treatments you can take but firstly you should find a doctor! Baby dust and best wishes to you!
I agree with kindergal, I don't think you'll get any testing done until it's been a year since you started trying. The reason for this is that it's normal to take up to a year for a healthy couple with no fertility issues to conceive. So 7 months is not considered that long. However, if you still haven;t gotten pregnant after one year of trying, I would set up an appointment with your obgyn first, and then he/she can refer you to an RE if needed. Good luck to you!
Ok, so I should just try and find an OB/GYN to see?
You need to find an OB/Gyn or an RE. At your age, your Dr. most likely will not do any tests or anything until you have been trying for one year. At that time, you and your dh can begin fertility testing.
