What did every else do?

so the last week and a half have been hell for me and my partner. I was due on the 15th of Feb and my period didn't show I had a faint positive on the 16th and on the 17th I started bleeding. I went to the doctors on the 19th and was sent to a&e; as suspected ectopic as I was in a lot of pain in my left side and tested negative for pregnancy they sent me home when I had a negative. I was still in a lot if pain. I have been in and out of hospital and they done a scan and they found fluid in my uterus and put the pain down to another flair up of my pelvic inflammatory disease (have suffered for years since having my son) they gave me antibiotics intravenously and said it should help. what my question is: this worried me and my partner as we have been trying for 9 months and no luck and we want to start trying properly as in doing ovulation test and knowing when to bd and maybe getting pregnacare can I have some advise please? what helped you ladies conceive? Thank you
