I was suppose to get my period a couple of days ago still nothing....had to put on my <a href="https://play.google.com/store/apps/details?id=com.glow.android">glow app</a> no period today. I think my last period was around 1/5-1/9. Lately I have been so nauseas, my boobs are tender and sore not terrible lately but sore. I got these symptoms on 2/5/18. During this time I did have cramps one day thought I would get my period but nothing. Now today 2/14/18 I’m so tired, I eat and then feel like I need to vomit, my stomach has been hurting me I’m exhausted....I took a test negative. Not sure what’s going on!! Advice.
