irregular periods? endonetriosios? who should I go to?

Hi,
Welcome to ehealthforum,
If you are on the hormonal contraceptive pill for regulation of periods, chances of pregnancy are less. Causes for irregularity of periods could be many. If you are trying for pregnancy, you should consider visiting your gynecologist/obstetrician for further evaluation to look for the underlying cause for the irregular periods. Since the symptoms are worse around period time, chances of endometriosis, adenomyosis, pelvic adhesions, severe PID should be confirmed/ruled out by getting laparoscopy done. Treatment as appropriate (based on the examination findings and investigation results) would be started to help you in regulating your periods and help with getting pregnant.
If pregnancy is suspected, look out for development of any other new symptoms suggestive of pregnancy and consider visiting your gynecologist at the earliest for thorough examination (to confirm pregnancy related changes/signs in body) and blood/serum HCG level test (to confirm/rule out pregnancy accurately). Be in regular monitoring and follow-up with your treating doctor/gynecologist and report any new/abnormal symptoms immediately. Take adequate rest. Drink plenty of water. Maintain healthy diet and lifestyle.
Take care.
