Worried.

So this might be some TMI but my husband is away in missouri for college he came down the 14th of decembee and stayed with me until the 13th of January everyday we have had sex, sometimes more then once. We bought prenatals to help concieve starting about 2 days ago i have been feeling nauseas, i get tired very early, ive had headaches, and terrible mood swings. Im anxious to test because it seems like everytime we think im pregnant i start to bleed. I need confrontation on what i should do. On this app it says my period isnt due for 4 more days..and advice? I have a dr apt today at 11 for a cold should i talk to him?
