Has anyone ever had leg pain only when they lay down?

I’m currently 15 weeks about to be 16 weeks in 2 days and for a few days now ONLY my left leg has been hurting and it only hurts when I lay down. When I’m standing or sitting there’s no pain in my leg at all but as soon as I lay down my leg just starts to hurt like hell and I try laying on right side and it still hurts because I thought it was me laying on my left side that caused the pain. There’s literally nothing I can do and my boyfriend’s aunt suggested tylenol and I took 1 but that did nothing. I’m losing sleep because this is very uncomfortable and I’m just hoping I’m not the only one who’s experienced this.

P.S. this is my first pregnancy 🤰🏽
