I had physical relation with my girlfriend on 26/6/18. We did a protective one and used a condom. Her periods cycle is getting affected now as they happen on 7th of every month and last for 2 days but this time it did happened on 7th night and ended the next morning i.e on 8th.
What may be the factors ? She also did a
pregnancy test on 11/7/18 but not on empty stomach. The kit showed nothing.
We are worried. Please help
