TTC? Endo?

Toni • Mother of Isabella aged 3. Pregnant due July 16
Had endometriosis removed in September, my periods returned back to normal straight away literally to the day which I was lucky with I no.. So me and my partner started trying for a baby month ago.. Now I am over a week late with lots of pregnancy symtoms sore boobs n discharge etc.. 4 negative pregnancy tests now terrified is endo back or what's going on 😒😞
