Worried ?

Hi po. So, 1 month na si baby ko. Normal delivery and alam ko medyo maaga pa for it pero me and my husband had s*x already. 1st nung 3rd week ni baby and 2nd was the day before yesterday. Pag una papasok masakit, and di minamadali pagpasok kasi nga iniisip yung tahi. Ngayon, kanina madaling araw. Nagyaya ulit sya. Ok naman, nakapasok kaso dumulas and natamaan yung tahi ko nung susubukan nya ipasok ulit. We stopped kasi sumakit talaga tahi ko. Should I be worried? May chance ba mag open ulit tahi ko?
