Pelvic inflammatory desise

Chloe • Been together 6years haven`t started trying just yet but our considering a baby soon might in the next few months
went to the clinic not far from me and got told I had a swolen cervix I'm not sure how I have got this as me and my partener have only slept with each other:-l   The clinic gave me 2 types of tables I've doxycycline and metronidazole 1of each of a morning and one of each at night I was wondering if I could take my morning 2 at 9/10am and my night to at 3/4pm As it makes me have panick attacks and feel realy uneasy when I'm sat about but feel a little sicky and nothing else when I'm active and have my mind on somthing else
I started on Wednesday 28 and took both my doses I was told to 
Thursday I took my morning ones and felt like I was going to pass out and felt realy sick so didn't take my second dose 
Friday 30th I plan on taking both doses why I'm active messing around 
If anyone else has taken these before it had what I'm experianceing could somebody advise me if I can take both sides during the day so I'm not on edge taking them at night??thanks
