Thanks for your query.
I read your query and I understand your concerns.
Following is my reply:
1) Please get urine pregnancy
test for confirming pregnancy
2) If not pregnant, wait for 5 weeks by which time you might get cycle.
3) Cycles vary once in a while. Hence I advice you not to worry.
I hope I answered your query. I will be available for any follow up query you have.
