I need answers :(

So my husband and I had sex three times during my ovulation week the last week of September. AF started October 10th and lasted till the 16th. Normally my period lasts for around 7-10 days and is very heavy. However, that period was very light and didn’t last as long as normal. I started getting very nauseous and was throwing up and also started to become very tired, to the point where I would go to bed by 10pm and sleep till 11-12 in the afternoon. I took a pregnancy test and swore i was a faint line. (look at picture below)

So after my weird, short period, we had little sex during my next ovulation window because I had my first ever yeast infection. I also still was very sick and still throwing up and had horrible headaches and still was very tired.

Fast forward to now. My period was supposed to start November 10th. It didn’t start till November 12th and it was once again very light, not heavy. No clots like i would normally have. Basically spotting. I have on a light pad and change it once a day but barely has anything on it. I am still sick. I have been throwing up more and doing anything at all makes me nauseous. I don’t know what to do. My friends and my mom think i’m pregnant but i have been spotting so I feel like I can’t be pregnant. Has this happened to any of y’all?
