Stress and antibiotics causing missed period ?

User Profile
Hi, i am a 19 year old female not on birth control, and i have missed my period by 4 days now. the last intercourse i had was precisely 4 weeks ago with my boyfriend, and right when my app predicted my ovulation (around 3 weeks ago) i got diagnosed with a kidney infection and was on amoxicilin (antibiotics) for 10 days and also heavy painkillers. now that my period is late i am having all the symptoms i normally have before my period, and i got very stressed so i took two pregnancy tests on the third day that my period was late and they were both negative. is it possible that the stress and the use of medicine threw off my cycle? the sex was unprotected but i am 100% sure that there was no ejaculation inside, i just want to know if its normal that my period is late and what the cause could be. thanks!

Thank you for asking at Ehealth forum!

I read your question and I understand your concern.
The delay in cycle could be due to diverse reasons and apart from pregnancy,it can be due to weakness, medication,stress, anxiety or tension.As all pregnancy tests are negative here,we can presume the chance of getting pregnant is almost nil.You need have to wait for a spontaneous cycle which might come over next one week.

I hope it helps. Stay in touch with your healthcare provider for further guidance as our answers are just for education and counselling purposes and cannot be an alternative to actual visit to a doctor.
Take care
