Advice please 😣💕

Okay so recently I've found out im expecting..(first child) I started spotting the other day so my midwife told me to keep an eye just in case..The spottimg was light an actually stopped after an hour I'd say...so i put it down to implantation bleeding....But tonight me an my partner ended up having sex an once we were done he noticed blood..So I went to check...It was light pinkish but I'm just a little worried...Have anyone else had this before?? Is it normal?? I'm new to all this, can someone help?? TIA x
