Hi i am trying to conceive. i am expecting this month but i have the feeling of getting periods as like pms. i have increased appetite and thirstiness?

If you miss period: PMS is not the important thing - your period is. If you do miss it this month - do a test or see a doctor. Ask for clear info while you're there. Unprotected intercourse at or near ovulation by a fertile man and woman brings a good chance of conceiving. Soft signs like appetite/thirst are not good indicators of pregnancy. Again - if you skip a period - have a test. Good luck!
