first time

so i had my mirena iud removed april 10th. i had a regular period throughout the 3 years i had it. i had the removal bleeding from the 13th-15th. we did the deed 16th and 17th. my period came a couple days earlier and lasted for 4 days which is my normal. we did the deed the 26th 28th and the 30th. for the last week i’ve done nothing but feel so nauseous and bloated. i’m cramping and most of the time feel like i have a balloon full of water in my lower abdomen between my hips. i don’t know if i passed ovulation or not. i use the simple pee tests as it’s easier and they all come back with lines but nothing as dark as the control line. i have two ovulation apps i use to tract what’s going on and both show i am ovulation currently. i have watery/stringy discharge. my period isn’t supposed to come till the 16th of may. i don’t know what’s going on but i’m so frustrated
