QuestionI have reoccuring sinus infections and have been on antibiotics for 4 weeks now. I am on birth control, however my Fiance and I haven't used any other method of birth control. Begining last Thursday I began getting nauseated and throwing up several times a day, this has continued until today. I took a pregnancy test this morning, but it was negative. If this is morning sickness shouldn't I show a positive? The antibiotic I'm on is doxycycline, I have only had one dose since Thurs. Could this still be from the anibiotic?
Answer This could be several things, it could be from the antibiotics, it could be a stomach bug, it could be pregnacy.
The best thing if you think it is pregnacy is wait one week from the last test and test again.
If you are not wanting to get pregnant a backup such as condoms is a good idea.
Good luck to you!
