. I need some opinions here . 🙈Currently I am ttc . I was hoping to start this month and I was expecting a period around the 14-15th of February. Well that week I ended up with a uti infection .. I was prescribed antibiotic. I started taking the antibiotic on the 14th of February my first dose . The day after I started to spot like brown stringy stuff it was only when I wiped to use the bathroom nothing at all to use a pad . That lasted about 4 days . Just spotting nothing like a normal flow . So from the 15- 19 I had just spotting . I am unsure if the antibiotic messed with my cycle 😏🤔 that hasn’t happened to me before . So on the 20th I had a heavier bleed I had to use a pad and that lasted like two days and it was over . The 22nd all my bleeding stopped . I just don’t know if I should calculate my period starting the 15? Or when my flow was heavy on the 20th???? What do you all think I should do . I have had unprotected sex a few times already .
