Lightening pains at 30weeks??

Is it too early to have lightening pains already? This is #3 and when I went to my ultrasound the other day she was head down, face down (which I know this early doesn’t really mean anything lol) but I also talked to my doctor about how I’ve been having pretty strong bh contractions pretty frequently and she told me to keep an eye on them and to go in to be monitored if they get worse. I didn’t really think about it when I had one or 2 but the pains are starting to happen more often each day. Anyone else have this with their other pregnancies this early?
