You have given a rather confusing menstrual history. But, I'll try to help you. You are not on pills after you last finished your pill on 29th June. Let me tell you that post-pill the fertility
increases. You should have a urine test done for confirmation of pregnancy
with a sample of the mid-stream urine collected hygienically. If the test is negative and you do not menstruate for another 15 days ( since you said don't mind getting pregnant ), repeat the test or get it done in a laboratory.
In case your test is negative and you do not get menstruation
, you should visit an emergency room or see a gynecologist. Get USG of the uterus
done to investigate the tubes, uterus and ovaries or any tumour. You may need a per vaginal or rectal check up to get treated according to the diagnosis made. Do not worry, have a little patience you will be fine soon. Take care.
