help me!!

Okay ladies so I haven't seen a normal period in 7 weeks usually I see one in 6 weeks on the third week I started spotting and was spotting on and off for 2 weeks and now I'm having terrible insomnia (3 hours sleep a night and a 8 month old to get up too). Please tell me someone else has been through the same thing it's the insomnia that's getting to me! I'm utterly exhausted but I can lye here for hours and not go to sleep until 5am and then get up at 8am and repeat 😩
