What’s going on????😣😣

So my last period was in December during Christmas time. And after that I’ve never gotten my period again it’s been 2 months since and I never had irregular periods... my periods are normal but I’m just confused like I have token 3 pregnancy tests and they all came back negative so should i go to the doctor to go take a blood test or should I just wait ???? ( Plus me and my husband are TTC right now)
