You should talk to your doctor about finding out if you are ovulating. Since you've been trying for 2 years you definitely qualify for being referred to a fertility specialist. I know thyroid issues can make it harder to conceive... but not impossible (unless there're other issues going on).
I got pregnant in 2 months, using mymonthlycycles.com
I am regualr though so I suggest you go to the dr.s to see if you are even producing eggs and ovulating. they may make you take fertility meds. GOOD LUK!
Have you tried charting? There are several sites online that can help you with this, including I believe medhelp! It takes ALL of your fertility "clues" (CM, CP, BBT, etc...) into consideration and helps you decide which days are your most fertile so that you know the best times to BD! I've also heard that BD'ing every other day can do the trick (that worked for me!)
I agree with Joy too, talking to your Dr. can't hurt. I'm sure that they can help you with more ideas or even meds if needed to help you TTC. Good Luck!! And let us know how you are doing!
Hi my name is lizeth but u can call me liz. well im 20 and my husband and i were trying for 2yrs and finally in may i found out i was pregnant but i had gone to my doctor and asked for a refferal to a OB/GYN to see what they can do to help us. well like you i am irregular when it come to my menstrual he said if you are irregular you either dont ovulate or dont ovulate enough eggs or every cycle. so he suggested clomid. worked for us on the first try. Clomid are pills that help u ovulate properly so you take the first pilll on ur 4th or 5th day of your period and contiue till ur done with the pills. im sure ur fine and ull concive soon.
