My husband and I have been TTC for a year and 6 months. I am only 20 so I didn’t expect to have issues trying to get pregnant. My husband is 27. I have tracked my cycles long before we started trying so I obviously have still been doing that and have been having sex on the predicted ovulation days and days leading up to it. I have also recently been using OPK strips to predict ovulation. My cycle is always regular. Obviously I know people on here have been trying for a lot longer than we have, but as it’s been over a year we are starting to get concerned... when should we consult with a doctor about this? Should I just stop worrying and keep trying? Is there a certain amount of time to try before you begin to consult doctors?
