Help??

Last month Or 2 i had sex and ovulated 2/3 days later as I tested OPK and got a positive & I was late on my period last month so I tested and on day one and got a faint positive. And for 5 days straight I got only faints. On day 5 I got what I assume was my period except it was so different. It lasted a week or so it was super heavy I had tissue looking clots & tested and got a negative after that. Well back to this month.. I'm 12 days late I had sharp pains lasted 30 minutes one day and now I'm suppose to start ovulating again even high I have t got my period as glow predicts & I tested and keep getting faints. On pink dyes I get negatives & on blue dyes I get faint positives. I'm not stressed or anything I feel perfectly fine except sometimes I get bloated or have cramps and sometimes discomfort when I lay on my stomach. Can any one give me advice on what's going on? Has any one else experienced this ?
