my last period was sometime in the beginning of feb. i have very irregular periods anyways so its normal for me to go a month w/o a period, so i didnt think to much of it at all when i was a month late. then when i was 2 months late i didnt think to much of it then either b/c there was 1 other time i was 2 months late, so i just shrugged it off as maybe stress or whatever. then the 3rd month i still didnt get AF so i took a hpt and of course it came back negative. then at the beginning of this month i went to a prengnacy center where i had a urine test done and it came back negative, then this past tuesday i went to the docs and had a blood test done, but im still waiting on the results from them which hopefully i will get tomorrow, if they dont call im calling them to find out. the dr. told me if it comes back negative then im not pregnant and he wants to start me on some pills to get my period started back up. but i have read to many forums of women who have had negative blood tests and end up being pregnant anyways. also ive read of women who kept getting negatives and then finally have an ultra sound done and find to be 2-4 months pregnant. ive also read some other things it could be like cysts or ectopic pregnancy. it has me so worried. i dont know what to think. what do u all think?
