Implantation bleeding. So confused

Krystal

Hey everybody I’m 36 will be 37 on the 19th of this month. I’ve been ttc with my boyfriend for a lil over a year. I was Red from the 24/29 of January. I ovulated on the 3 and now I’m spotting and cramping but glow and my other app both says I’m supposed to start on my birthday. I don’t know what to think. Any advice would be appreciated. I do have 2 daughters 16/15 this would be number 3 I just don’t know what to do or think
