need advice asap!
Me & my boyfriend broke up at the beginning of February 2018 , I was on the contraption injection waiting for it too wear off so I could have regular periods .
Whilst me and the boyfriend was broken up I slept with a guy on the 20th feb 2018 with a condom, then ended up getting back with my ex(the boyfriend) on the 23rd of feb and have been sleeping with him unprotected since. I found out I was pregnant and I panicked because Of how quickly it happened after me and my boyfriend had been trying for a year. Is there a possibility the baby could be the one night stands or am I just over thinking . I’m 18 weeks + 1 day and the midwife said the first day of my last period was the 22nd of feb however I didn’t have a period because my periods are irregular since coming off the injection! Please help me out and be honest !
