Hello,
Thank you for your query.
It is possible to be pregnant if you had intercourse during your fertile period (ovulation day and 3days prior to that).
This is usually in the middle third of your cycle.
The spotting,
vomiting don't seem related to
pregnancy. It could be an isolated incident.
A sure sign of a possible pregnancy is a missed period and positive pregnancy test after you have missed your period.
Please take a home pregnancy test to check, once you have missed your period.
If negative, I recommend :
-
basal body temperature monitoring & using
ovulation prediction kits to detect ovulation day.
This day and the three days before that are your most fertile period.
-regular intercourse (every alternate day) in the middle third of your cycle (day 10 to 20 in a 30 day cycle, for instance).
-minimize caffeine
-maintain healthy diet and weight.
-exercise regularly. Don't
stress to much while trying. It doesn't help and Infact can negatively impact
fertility.
-take a
folic acid supplement everyday.
-if below 30 yrs, try for a year and of above 30,for 6 months before seeking professional help.
It will happen. Keep trying. Don't get frustrated. Take a break of the pressure of trying to conceive gets too much.
Hope this helps. Wish you well.
