I'm really sick and need advice (so plz cut me some slack)

Happend on First day of period/spotting. (April 28th-29th)
Period lasted 5-6 days after the inccedent (stopped bleeding on may 2-3rd)
Man had ejaculated night (thuradays april 27th) before and had been pee couple times since then before following night we did this. (April 28th)
Clue/glow predicted fertile window suppose to start 10-11 days after incident (was targeted to start fertile window may 8-9th) 
Ovulation pridicted for 15-16 days after the incident. (May 13-14th)
So a total of perashpse 14-17 days passed between day of iccdent and ovulation. 
Man or I toched clit/labia/vuvla on accident and some could have gottom on outside/inside me. On april 28th
21 days latter (may 18th) 9 days before i'm due for period) I took urine lab test at hospital. It was neg. 
I'm on antibiotic and steriods (shot that realses over 5 days, fluid steriods yesterday for few hours and now 20mg 3x day for ten days as of yesterday) so ik it could postpone my upcomimg period which is suppose to start in 9 days. On top of that i got high wbc count, infections, bronchides, and inflamed and constricted airways. So please no bashing. 
So, since it happend first day (april 28) of period, i bleed for 6 days after, wasnt suppose to ovulate for another 15-16 days (may 13th), and 21 days later hosp. (May 18th) Urine test was neg. should I even bother testing? 
As tou can tell I know it may be slim but i'm worried and really sick and need to know if i should even attempt
To get a home test if i'm late (which ik steriods may cause me to be) and yes, i know how children are made, etc. getting on copper bc maybe or shot. 
I also been having egg white globby cm see below.
