93 days no period

Last period was in February.. its possible i could be pregnant but been to doctors 2 weeks ago for urine test and came back ñnegative. Now i keep getting sick over the smell of food and my boobs have all of a sudden grown much bigger. Also getting bad stomach cramps. Is it possible the test could be wrong? Are my symptoms similar to those who have pcos? Any help or information would be kindly appreciated!! Got a doctors appointment booked again for the next few weeks but just wondering if anyone else been through the same. Xx

Edit also had blood test done but they were checking for hormonal inbalance etc. Would it show if they wasnt looking for pregnancy to come up on bloods?

Bloods came back all ok
