Do I need to go back to my doctor for sinusitis do to the fact the antibotics he
Gave me did not work, or can I take some over the counter medication?

If the Doctor gave you antibiotics he/she has diagnosed an infection. How long have you been on the antibiotics? The course is very often 10 days.

Over the counter drugs will not handle an infection.

Hi I have suffered from bad stomach cramps all weekend. What could this mean? Could I be pregnant as this was how my sisters pregnancy started.
