Ovulation?

Y’all I’m going on 7 days of cramps but yet my period is in about a week or 2, I’m irregular, I thought maybe it’s cos I was getting my period early since it’s all over the place since I gave birth to my son 11 months ago. Last month I got my first actual period with heavy bleeding and for 5 days so I started taking ovulation tests and ran out but the last one I took was positive and hubby and I bd but now I’m thinking if this cramping is normal, it’s not bad but it’s uncomfortable and if i press on my belly it’s sensitive. I’m thinking if maybe i ovulated late and i read the test wrong or if maybe it’s implantation?? I’m just so lost I don’t remember this happening when I was pregnant. Has this ever happened to anyone
