Hi there, I have understood your concern. I will suggest you the best possible treatment options.
1 ) First of all all do not panic.
2 ) As you have negative
pregnancy test, you can assume that you are not pregnant.
In case of doubt blood
beta HCG test and USG will be of help.
Usually, blood beta HCG test done 10 to 12 days after the last unprotected sex act, will be of help. Values less than 5 indicate that you are not pregnant. and values above 25 confirms the pregnancy.
3 ) Even if you are pregnant, you can opt for termination of the pregnancy with medicines safely till 9 weeks of pregnancy under medical supervision. .
4 ) If depo injections are not suitable for you, you can opt for
oral contraceptive pills - birth control pills.
These pills will help to regularise your cycles and will also prevent the pregnancy.
5 ) Lastly your abdominal symptoms can be due to some gaseous movement of the intestine. Please avoid taking deep fried foods, bakery products and refined sugars.
Use of prebiotic like Lactobacilli capsules for a week will be of help.
I hope this answer helps you.
Thanks.
Dr. Purushottam Neurgaonkar.
