I had sex May 6 with protection and took Plan B just in case on May 9.

By May 18th, I had my period as regularly scheduled but took a pregnancy test on May 23rd just in case it was implantation bleeding (as my periods are sometimes heavy, sometimes light). The test came out negative.

I then had my period again around June 11th as regularly scheduled. My cycle is around 3 and a half weeks... it's been like clockwork for the past 5 years.

It is now July 17th, and I still have not had my period. I should have had it by the 5th. Could I be pregnant despite having my period twice on time? I have not had sex since May 6, so is this a possibility? Or could my missed (hopefully late) period be due to something else?

Any help would be greatly appreciated.

The Plan B pill should have taken care of the possible pregnancy, so I would say no, you are not pregnant.

Stress, diet and certain medications (Including Plan B) can throw off your period.

Take another HPT, just to clear your head and make you feel better. Make sure you use your morning urine as it is more accurate. If it comes out negative, see a doctor for other options on why your period has not shown up. :)

Same thing is happening to me right now... I took plan b two days after having sex and I got my period 5 days later. It lasted for 4 days and than I got another period a week later. Now its been 32 days since that last period. I'm late. Just wondering, what ended up happening for you? Did you get your next period finally?

Had sex on 14feb received my periods on 28th feb.after that I have not seen my periods up to now 16feb.cud I be pregnant

I've had my period twice since the last time I had sex (it was unprotected but he did not ejaculate inside) and I took four or five pregnancy tests ever since and they all came negative. However, this month, my period is late and I feel like I gained some weight (it might e due to quitting smoking, I don't know) My breasts are soar and I am getting some cramps. Is it possible that I'm pregnant??

Hello, my girlfriend and I had sex in jan. she took plan be and it was all good. Then again in feb. we had sex again and she took it again. After the second time taking it, her period moved from arjound the 20th to around the 7th. A few weeks ago we had sex and used a spermicidal condom and I did not ejaculate in her. Now her period is a week late and I was wondering if all the hormones from taking plan be twice in two months are just now settleing down and her period is going back to normal or is she pregnant. Thanks!
