Is it too soon to go & see the doctor about infertility?

I would go now, just because it doesn't hurt to find out there's nothing wrong, and if there is something wrong with either one of you, you can find out. Drugs like Clomid work for most people who don't ovulate normally. Charting isn't very accurate and there's so many things that can affect it. OPK's aren't all that accurate either, in fact even if it says you ovulated you may not have. I have PCOS (Poly Cystic Ovarian Syndrome) if I hadn't diagnosed myself no one else would have, I'm not over weight, but I have the rest of the symptoms. 1 in 10 women of reproductive age have PCOS many don't even know it, some women continue having regular menses even though they are not ovulating regularly. Have the doctor do a hormone test. If you do decide to take Clomid or other fertility drug, they are all available w/o a prescription in Mexico and they are extremely cheap just go to any large looking pharmacy and look for the name brand, Clomid is Omifin; just read how to take it. If you don't like the do it yourself method, try to get your doctor to at least do the blood tests to see if there's a hormone imbalance. Good luck.
