Advice on doxycycline and ttc

Hiy right this is my 7th month ttc and I've been prescribed antibiotic doxycycline have to take one in the morning and one in the evening for 7 days I started taking them today so will finish taking them on Monday. I'm due to ovulate the Monday after so 6-7 days after my last lot of antibiotic will this affect my chances? I've read it won't but just worried and really hope this is my month. Also can I still take folic acid eventhough I'm taking doxycycline
