Help.

So my boyfriend confronted me this morning about not having sex as often, which doesn’t bother me. But his reasoning is because he doesn’t want a baby right now. Which is fine but We had sex on my ovulation day, I have been spotting and felt fatigue, hunger, and anxious. I’ve gotten hot flashes multiple times. But I’m not sure what’s going on completely. I have PCOS and hypothyroid and I’m trying to concieve. Any advice would help.
