Blood is ruining my sex life 😔

So it's not uncommon for me to bleed after sex around ovulation time. A few days ago I bled quite bad.meaning the sheets etc all had to come off to get washed quickly. My husband found the amount of blood quite frightening and has been avoiding having sex with me since then. I have reassured him I am not in pain and its nothing he's doing wrong. Anyway ... this morning we done the deed and he admitted to me that half way through he thought I got suddenly really wet and it turned him off thinking it was blood. I reassured him again that I wasn't sore and I was okay. To be honest I was quite scared to look but didn't want to ruin the moment. Turns out I was bleeding again and needless to say he seen it. Does this happen to you and how do I solve this? P.s I have been on 3 lots of anti biotics recently so 100%do not have an infection of any kind.
