Did he draw blood? Have your doctor do pregnancy test using your blood.
i beleive you not trusting the doctors. its like you know your body and you know when something is going on in it. im three months late for my period and im waiting on results from an ultrasound all my tests has came back negative including my blood test. I found out that it is hard for the hcg level to be read these days becasuse all the hormones in foods that we eat can actually had that hormone. Like I have read stories after stories were people don't find out they are pregnant until about 5 to 7 months into their pregnancies. Which ***** for ppl that want to take care of there bodies while pregnant. I have went from an 36 c to and 36 d got new 36 d bras and can't were them now so now i have to get my breast size again. the 36 d make it look like i have four *******. I have found out that even the ultrasound want help me out right now if the baby is in that back doing the ultrasound. So if i still don't get an period and still have symtpoms that i might have to do all the blood work and ultrasound over again. I hope that this was some kinda of help. Everybody body is different and reads differents just remember that when taking advice for the internet.
Zantac is fine in pregnancy. So is Tums. Have a beta blood test done and get the exact amount of hCG in your blood. If it's 5 and under you're not pregnant.
