Need advice

In the month of October I had two periods one on October 2 and the second one on October 27 I thought it was a little weird because that has never happened to me. In the month of November 21st I started to spot a few drops and I put a liner on just in case. This morning I woke up went into the bathroom and I noticed only a few drops and when I wiped myself there is light bleeding but that’s pretty much it I’m have many symptoms such as breast tenderness, fatigue, cravings for salt in eating a lot of food feeling bloated all the time. I’m not to sure if this is a start of a period or I’m pregnant? I’m not really sure what to do? I was thinking of buying a cheap pregnancy test and taking it after the spotting has stopped in to see what is going on if it gets heavier or it just stops. I really don’t want to tell my husband because we would’ve been trying to for almost 10 years and in the meantime we had two miscarriages. I just need advice and support.
