Can you ovulate right after period?

Hi,
Welcome to ehealthforum,
The usual fertile days for a regular menstrual cycle of 28-30 days, would lie between day 8-18 taking day 1 as first day of bleeding (at times you can also have early ovulation). Sometimes ovulation can be accompanied by cramps and spotting. If you have been sexually active, then absence of pre-menstrual symptoms and altered periods could be suggestive of possibility of pregnancy and implantation. Visit your doctor/gynecologist at the earliest for further examination and investigations to look for the underlying cause. Treatment as appropriate (based on the examination findings and investigation results) would be started to help you. Be in regular monitoring and follow-up with your treating doctor/gynecologist and report any new/abnormal symptoms immediately.
If pregnancy is suspected, look out for development of any new symptoms suggestive of pregnancy. Wait and watch for your next periods. If you do not get your periods within 10 days of expected period dates, or if you get abnormal periods, or if you develop symptoms suggestive of pregnancy, you should consider visiting your gynecologist for thorough examination (to confirm pregnancy related changes/signs in body) and blood/serum HCG level test (to confirm/rule out pregnancy accurately).
Take care.
