Great timing — I fussed over this exact question while getting ready for a baby, so I’ll share what I learned in plain terms. Seven Seas' Omega-3 Max Strength is the kind of fish oil supplement that can be perfectly fine in pregnancy, but the safe bit depends on dose and what's actually in the bottle.
Look at the label first: check the amounts of DHA and EPA per capsule, and whether it’s a standard fish oil or cod liver oil (cod liver can contain vitamin A, which you want to avoid in high amounts during pregnancy). Most pregnancy guidance encourages a steady DHA intake — usually around 200–300 mg a day — because DHA supports fetal brain and eye development. If your Seven Seas capsules provide a good chunk of DHA and the product is purified (low mercury, third-party tested), taking the recommended number of capsules to reach that DHA target is generally considered safe.
One practical note from my own experience: I double-checked with my midwife, kept to the label dose, and avoided doubling up with other high-dose omega formulas. If you’re on blood thinners or have a bleeding disorder, check with your clinician first since fish oils can slightly increase bleeding risk. Personally, finding a prenatal supplement that combined folate, iodine, and the right DHA made me feel more relaxed than taking a standalone 'max strength' bottle, but the Seven Seas option worked well for topping up when needed — it gave me peace of mind during late-night reading about baby nutrition.
