it takes a normal couple from 1-2 years to conceive, 2 months really isn't that long. You would need to check when you ovulate, how many days cycle you have, are you regular or irregular. Some women have irregular periods when they first come off of bc as their bodies are trying to adjust.
The fact your only 18 years old means it might happen quicker for you but don't rush it, just let nature takes its course it will happen when it happens. Best of luck
on average it takes a couple like a year to conceive so dont get stressed out now lol. theres only a 25% chance you'll get pregnanct during each cycle so it is a lot of work. you could be having some of those symtoms because you are tying to get pregnant, or if you recently went of birth control.
Don't get stressed out if it doesn't happen right away. From what I heard some women increase there chances by getting to know there cycle and try to pinpoint exactly when they ovulate, if you know when you ovulate it's good to BD the day before, day of and day after.
I would go to fertility friend .com and get a chart set up and take the course to learn about your cycles. You can read all you want but what your baody does is waht you need to be learning most. I would say that becasue you are trying and hoping is why you ahve symptoms. LIke all the other posters said don't worry for a year and just relax!!! Trying hard can hurt the process also as your body needs to relax. Just give it time and don't worry about it yet.
