A few questions....

Hey guys :) My name is Jess. I am 22 years old and my boyfriend and I have been trying for a baby now for nearly 4 months... We haven't been lucky yet, but my period comes later and later each month and sometimes it just doesn't make sense... Has anyone else had weird experiences with their cycle while trying to conceive? Also does anyone have any tips on conceiving? My boyfriend and I are both trying to quit smoking, and we have pretty much stopped, and we are trying to make our bodies healthier each day. I also take prenatals and folic acid vitamins every day. Any tips or even kind words of encouragement would be great! We want our daughter badly💚🙌
