How long have you been ttc? I takes the average healthy couple a year to conceive, after a year you should see a fertility doctor. For me personally it took 11 months. 11 months of doing literally everything in the book to try and get pregnant. Then on our 12th month we tried preseed and bam we were pregnant. Were you on birth control previously? That plays a big factor too, some birth controls make it harder to get pregnant right after you stop them.
