Pregnancy v. menstru. These symptoms could be as simple as pre-menstrual type symptoms or they could be due to early pregnancy. Given that your period is late, why not take a home pregnancy test? Get lots of rest, drink lots of water and take 600mg Ibuprofen for abdominal cramping. Given what you describe as your alcohol intake, you could be dehydrated, make sure to drink, exercise and flush out your system.

If I have had three negative pregnancy tests but I have abdominal pain, morning nausea, vomiting and dizziness and no period could I still be pregnant?

Get blood test. If you had unprotected sex since your last period and have missed a period, you may get a blood test for HCG to test for pregnancy. A negative result on pregnancy test done too early does not rule out pregnancy. Home test should be done 4-5 days after a missed period. If the result is negative repeat it after another 4-5 days. Use first morning urine and follow the instructions for the test carefully. If you do not wish to be pregnant, use contraception all the time, every time. You may consider implanted contraceptive, or IUD. Practice safe sex. Get HPV vaccine. Read more...
