new ttc and issues with spotting

Lindsay
Hi ladies! I'm hoping someone on here will have had a similar experience as me to put me at ease because whenever I Google this stuff I go into panic mode.
I went off the pill in February and had my withdrawal bleed. My real period was 34 days later in March. I haven't had my period yet but I've been spotting almost every day for 3 1/2 weeks now. 
I'm not pregnant.
I went to the dr and had my ovaries and uterus checked for cysts or lumps and I'm okay.
My dr thinks it may be from antibiotics that I had a reaction to back in March. She says I should also stop running so much (was traing for a marathon). 
I stopped running a week and a half ago and I'm still spotting.
Has this happened to anyone else coming off the pill? My husband and I really want to start trying next month and I am so stressed out. 
Hope someone can help. Thanks! Xoxo
