Hi there,
After reading your query, my opinion is that:
1) There is very rare chance of
pregnancy when there is intercourse 2 days before periods.
2) The symptoms that you are having might be due to PMS i.e. pre menstrual syndrome. This syndrome occurs before menstrual periods and can cause breast tenderness, bloating, cramping, nausea and mood swings as well as food cravings. It occurs because of
hormonal changes similar to pregnancy so resemble pregnancy symptoms.
3) It is too soon to say whether you are pregnant or not.
4) You must wait for atleast 2 days after a missed period and get your urine pregnancy test done.
5) There is a
blood test called
serum beta HCG which gives a positive result sooner.
6) To know how far along you are, you would need to get a pelvic
ultrasound done, but it is not recommended to get it done before 4 weeks.
Hope this was helpful.
