Thanks Doctor for your detailed reply. We are not trying to have children at this time. I have a few more follow up questions:
1) What are the risks of receiving a condom protected oral sex? I will never do anything like that again but I just wanted to know the extend of the extreem risk I put her in?
2) Is it possible for women to have get an STD and a few months (4-5 months) later test negative?
It sounds to me as though you are concerned for your GF and perhaps rather guilty over your exposures outside of your relationship. From what you tell me however, there is no reason for you to be concerned that you might have given her something.
1. You exposures were condom protected. Condom protected sex is safe sex.
2. Proving that , you and your GF have tested negative for STDs. The tests are very, very good.
3. There are many reasons for a woman to have abdominal pain and/or intermenstrual bleeding. This includes resumption of taking birth control pills. If the GYN was not concerned, you should not be either.
4. There is no need for fertility testing. you did not say if you are actively trying to have children at this time and, if fact, mentioned that your partner has recently re-started taking the pill.
Try to relax. Your concern for your GF is to be congratulated but from what you have told me, there is no reason to worry. I hope my comments are helpful to (the two of) you. EWH
Some Additional Info
1) She had no discharge and no other episodes of bleeding after sex. That one episode she bled during sex and not after as I did see blood on my penis afterwards.
2) The Gyno gave her a pelvic exam and did say everything looked normal.
3) Is there a fertility test she can do?
