In-between Periods

I’m in between periods. Literally right in the middle. I’m kinda worried about pregnancy. My breasts are a little bit tender and my boyfriend noticed they were bigger. My nips don’t look different but they do kinda ache every once in a while. I’ve been nauseous for a couple of days, I actually vomited one day. I’m craving some foods and avoiding others. I’ve been having trouble sleeping the past couple of days. I take my birth control everyday but I went passed the exact time by some hours a few days in a row. I was bloated but it went down. It may be PMS but I’m not so sure this time.

Is it too early to take a pregnancy test? I haven’t missed a period yet.
