Taking pill regl?: If you are using the birth control pill, taking every day (!!) at the same time, and have been on for a few months at least then with this low dose sort, sometimes no cycle is ok, just the uterus lining got really thin. So, don't worry.
If this keeps up, tho, talk to ur doc who prescribes. You may want a pill with a little higher estrogen dose. ...Read more

I had an abortion about 25 days ago and my period hasn t started yet I had an unprotected sex an I used levonorgestrel after is it possible being preg?

Probably low risk: If you used Plan B within 72 hours of the sex, the risk of pregnancy is ~ 10%. But you may want to consider a reliable form of contraception so you don't have repeated pregnancy scares and end up needing another abortion. ...Read more

I had medical abortion 12 days ago, is it safe for my body to take Plan B (levonorgestrel 1.5 mg) with respect to future fertility? Thank you!

I had medical abortion 12 days ago, is it safe for my body to take Plan B (levonorgestrel 1.5 mg) with respect to future fertility? Thank you!

Yes, if f/u exam ok: If your doctor has cleared you that the abortion was complete, then Plan B as well as other birth control products can be used in the future without compromising your fertility. I strongly urge that you use some other birth control method and protected sex instead of Plan B for pregnancy prevention until you are ready to have a baby. ...Read more

I was on seasonique for 2 weeks and had sex and freaked and got Plan B just in case. The next day I had to start antibiotics. Is there a chance I could have gotten pregnant since antibiotics interact?

I was on seasonique for 2 weeks and had sex and freaked and got Plan B just in case. The next day I had to start antibiotics. Is there a chance I could have gotten pregnant since antibiotics interact?

Low risk: The birth control pills are effective 7 days after starting so it sounds like you were protected. Taking Plan B just is case is fine and lowered risk even further below pill failure rate. Most antibiotics do not interfere with birth control pills. Rifampin (a medication for tuberculosis) is the only antibiotic that decreases pill effectiveness. The antibiotic you were given does not. ...Read more

I have had mirena (levonorgestrel) inserted and am having issues?

What issues?: After an iud is inserted, it can take 3-6 months for the side effects to stabilize. For most of us, this reliable, carefree method of birth control is worth the initial suffering. But if you have fever, abdominal pain, or abnormal/foul discharge, i'd be worried about infection, and i'd see a doc. If it's just cramps, Ibuprofen and a heating pad can help. Mood changes and acne usually get better. ...Read more
