Jess,
Glad to hear that you are recovering well from surgery.
Women are able to conceive after they have chemo, in fact pregnant women have been known to have chemo without doing harm to the baby.
In a way being triple negative in this case means that you will not have to deal with hormone treatments like the aromatase inhibitirs or tamoxifen. It is those drugs that prevent ovulation and in some rare cases cause uterine cancer. But you will not be on those drugs and you should be able to have another baby in a few years. The chemo may affect your fertility for a while. Certain chemo combinations have a greater effect on fertility than others, your oncologist may be able to answer your questions.
Why don't you ask your oncologist to refer you to a fertility expert who can better answer your questions, especially if you test positive for the BRACA genes.
It is good that you have a positive attitude about your surgery and treatment. That will help you get through the chemo. Remember to take care of yourself and rest when you need to - it is important to keep up your strength. Also during chemo drink lots of fluids especially water and make sure you eat lean protein and plenty of fruits and vegetables.
Even if you lose your appetite - find two or three foods that you like and eat them - you must eat and drink lots of water during chemo.
See if your boyfriend can go to a support group for spouses so he can cope with his feelings. Many hospitals have such groups - ask your oncologist or call your local hospital or your local ACS chapter or even a Gilda's Club chapter in your area.
It is difficult for him to deal with your surgery, and treatment as well as his emotions at the same time. So he too needs someplace or someone to vent with as you have just done.
Please come back and let us know how you, and your boyfriend are doing.
Chemo is not an easy road - but it can be easier if you remain positive and take care of yourself.
Good luck,
Judy
