I got my last period on July 31st since i’ve been past due for my period i’ve taken one test and its been negative. I’ve not really felt any symptoms except for feeling nauseus on and off and being very very sleepy.

recently i’ve developed a canker sore in my mouth (I dont have any STD’s) and have come down with a bad case of gingivitis. I heard pregnancy can cause this symptom. i’ve also had bad acne which is not normal for me. i’m not sure if i am pregnant and dont wanna waste more money on a negative HPT. If i do decide to take one would it definitely show up positive if i was? Regarding the gingivitis.i have pretty good oral hygiene and have never had a problem like this before. It just started happening like three days ago after i went swimming. I went to work and noticed my mouth was hurting really bad. i’ve never been pregnant before and i’m not sure what to look for.

i know the usual signs and symptoms but everyone is different and i know some people dont feel much at all.

any advice would be helpful
