Help please

So I’m 7 postpartum ladies and I got my period in January and had unprotected sex within that time.. and March 25th I had spotting that lasted a day and I’ve had some pains in my stomach, tender breast feeling like throwing up but have had some food abbreviations... also I been feeling tired and having headaches but not sure if its because my daughter or maybe pregnancy or hormones.... please someone let me know... any advice tips is very helpful... have blood work scheduled!.

Thanks in advance .💕
